JEE Main Preparation Tips for Mathematics: Important Topics and Strategies

Mathematics is probably the lifesaver for a large number of aspirants of JEE Main. Preparation for JEE Main Mathematics is comparatively easier than the other two sections and due to a foundation based on Sets, Relations and Functions, the learning does not require to start everything from scratch. The first step that comes under the JEE Main Preparation Tips for Mathematics is to be updated with the syllabus of JEE Main Mathematics 2020. Being well informed with the syllabus will definitely help you work upon the most important topics.

Mathematics is yet considered to be hard because of the fear created out of it. In order to overcome your fear, you are advised to start preparing Mathematics pretty well in advance. Candidates are advised to practice a sufficient number of IIT JEE previous year question papers. When you will start regularly solving previous years papers, you will be able to know the type of questions, the patterns that might be present in the upcoming examination and will also be able to figure out your weaknesses and strengths. Let us start with some very basic JEE Main Preparation Tips for Mathematics.

JEE Main Preparation Tips for Mathematics: Basic Rules to Follow

  • Revision is Important – Organise your study time and revision time. Revision ensures you are on track with the topics that are not under purview but must be worked on. Take regular breaks and practice previous years’ JEE Main question papers. Revise the topics every alternate day or at least twice a week.
  • Topic-wise Mocks– Attempting mock tests and practice papers can actually tell what level of preparation is needed. Solving the question papers enables the candidates to know difficulty levels and their own preparation against it so they can work on their weak areas. With online mocks, a deep analysis is easily available online, to understand accuracy, strong topics, time-consuming topics and weak topics.
  • Speedy Calculations – With better practice, students will build speed in core topics. This speed must be maintained during the examination as well. Since there is no sectional timing, ensure that you solve enough questions from each section within 1 and a half hour (90 minutes) such that the score reaches the expected cutoff.
  • Accurate Answers – If you follow the speed rule in the first 90 minutes, follow the accuracy rule in the next 90 minutes. Instead of solving maximum questions, try solving what you can, but with accurate answers. This will help build your score and probably help in overall rank considered for IITs.

JEE Main Preparation Tips for Mathematics: Key Pointers

  • The trend of questions from previous year question papers can be analysed. Questions come from almost every chapter in the exam.
  • Apply for the official JEE Main Mock Test. It will help you overcome the nervousness of exam halls.
  • You cannot learn a formula by reading but only through practice. The more you practice, the better you perform.
  • Solve online mock tests on a table and chair. It gives an exam hall viewpoint and helps with time management.
  • The graphical approach helps a lot in solving Mathematics questions. If you can learn how to create a graph, many questions of calculus and trigonometry could be solved in a blink.
  • Hit and trial method works in some questions where reverse calculations might be time-consuming. Use it with care.
  • While solving questions, make sure the most common errors of addition, subtraction, multiplication or division do not occur. Marks in JEE Main are only for the right answer, none for steps.
  • Strengthen your grip on function theory because it is the foundation for almost each and every topic of class 11th and 12th.
  • If solving questions on a rough sheet, use as many sheets as required. Do not scribble over and over on the same sheet. One may never know when the answer might get mixed up with another question.
  • As soon as the timer starts on the computer, spend around 5 to 10 minutes searching for easy questions from all the 25 questions. 40% to 50% of JEE Main Mathematics questions are easy and scorable. Around 20% to 30% are moderate and almost 10% to 20% difficult.
  • Instead of getting entangled in tough questions, you must try to solve easy questions while giving two to three minutes towards each question. Approximately, 20 questions can be solved in 60 minutes if each question takes a maximum duration of 3 minutes. Every single mark counts. Don’t waste time.
  • Focus on the topics you have a good grip over. Pay attention to them. Memorise formulas and concepts of all the major topics.

By the determinant method, the area of the triangle formed by these coordinates comes out to be a2/112 which is equal to 7

This gives the value of a as 28.

Ques. If the line x=k; k= 1,2,3,…..,n meet the line y=3x+4 at the points Ak(xk,yk), k= 1,2,3…..,n then the ordinate of the centre of the mean position of points Ak, k= 1,2,3,…..,n is

1) n+1/2 3) 3(n+1)/2

2) 3n+11/2 4) None of the above

Ans. We have yk=3k+4, the ordinate of intersection of x=k and y=3x+4 . So the ordinate of the mean position of the points Ak k= 1,2,3,…..,n is

(1/n){sum of all yk’s} which comes out to be 3n+11/2

Ques. If the point (3,4) lies on the locus of the point of intersection of the lines xcost+ysint =a and xsint-ycost=b, the point (a,b) lies on the line 3x-4y=0 then |a+b|=?

1) 1 3) 7

2) 3 4) 12

Ans. Squaring and adding the given equations of the lines we get

x2+y2=a2+b2 as the locus of the point of intersection of these lines.

Since (3,4) lies on the locus we get

9+16=a2+b2

Also (a,b) lies on 3x-4y=0 so 3a-4b=0

Solving the two equations for a and b, we get |a+b|= 7

Ques. Equation of the circle with centre (-4,3) touching internally and containing the circle x2+y2=1is

1) x2+y2+8x-6y+9=0 3) x2+y2-8x+6y+9=0

2)x2+y2+8x-6y+11=0 4) x2+y2-8x+6y-11=0

Ans. Let the equation of the required circle be (x+4)2+(y-3)2=r2

If the above circle touches the circle x2+y2=1 internally, then the distance between the centres of the circles is equal to the difference of their radii

42+32=r-1

Which implies r=6

So the equation of the circle is x2+y2+8x-6y-11=0

Ques. If the normal chord at a point ‘t’ on the parabola y2=4axsubtends a right angle at the vertex, then the value of t is

1)4 3) 3

2)1 4) 2

Ans. Equation of the normal at ‘t’ to the parabola y2=4ax is y= -tx+2at+at3

The joint equation of the lines joining the vertex to the points of the intersection of parabola and the normal is

y2=4ax[y+tx/2at+t3]

4tx2-(2t+t3)y2+4xy=0

Since these lines are at right angles so the coefficient of x2+y2=0

So, t comes out to be 2.

Ques. The angle between a diagonal of a cube and one of its edges is,

1) cos-1(1/3) 3) /3

2) /4 4) /6

Ans. Let a= a1i, b=a1j ,c=a1k.

Then the vector d= a1(i+j+k) is a diagonal of the cube. The angle between one of the edges a, b or c and the diagonal d is given by,

cos=a.d/|a||d| which comes out to be cos-1(1/3).

Ques. Volume of the tetrahedron with vertices P(-1,2,0) ; Q(2,1,-3) ; R(1,0,1) and S (3,-2,3) is

1) 1/3 3) 1/4

2) 2/3 4) ¾

Ans. Volume of the tetrahedron is given by a scalar triple product,

Volume of tetrahedron= ⅙|PQ.(PR x PS)|

Here PQ, PR and PS are three vectors made from the above provided coordinates.

So, the volume of tetrahedron comes out to be ⅔ after solving the triple product.

Ques. If A,B,C and D are four points in space and |ABxCD+BCxAD+CAxBD|=(area of triangle ABC). Then the value of is-

1) 1 3) 3

2) 2 4) 4

Ans. Let D be the origin of reference and DA=a, DB= b, DC= c

So, |ABxCD+BCxAD+CAxBD|= |(b-a) x (-c) +(c-b) x (-a) + (a-c) x (-b)|

= 2|axb+bxc+cxa|

=2(2 area of ABC)

Hence equals 4

Ques. A unit tangent vector at t=2 on the curve x=t2+2,y=4t3-5,z=2t2-6t is?

Ans. The position vector of any point at t is r=(t2+2)i+(4t3-5)j+(2t2-6t) k

dr/dt=2ti+12t2j+(4t-6)k

At t=2, the above comes out to be 4i+48j+2k, and the unit vector comes out to be (1/580) 2i+24j+k

Ques. Let N be the foot of the perpendicular of length p from the origin to a plane and l,m,n be the direction cosines of ON, the equation of the plane is

1) px+my+nz=l 3) lx+my+pz=n

2) lx+py+nz =m 4) lx+my+nz=p

Ans. The coordinates of N are (pl,pm,pn) and let P(x,y,z) be any point on the plane. The direction cosines of PN are proportional to x-pl, y-pm and z-pm. Since ON is perpendicular to the plane, it is perp. To PN

Hence, l(x-pl)+m(y-pm)+n(z-pm)=0

lx+my+nz=p(l2+m2+n2)=p, which is the locus of P and is the required equation of the plane.

Ques. The image of the point (-1,3,4) in the plane x-2y = 0 is

1) 8,4,4 3) 15,11,4

2) 9/5, -13/5,4 4) 4,4,1

Ans. Required image of the line lies on the line through A(-1,3,4) and perpendicular to x-2y=0 that is on the line

x+1/1 = y-3/-2 = z-4/ 0 =t (say)

So, the coordinates of the image is (t-1,-2t+3,4)

This point also lies on the plane, so t comes out to be 14/5

So, the required image is (9/5, -13/5,4).

Ques. If (2,3,5) is one end of the diameter of the spherex2+y2+z2-6x-12y-2z+20=0 then the coordinates of the other end are

1) 4,9,-3 3) 4,3,3

2) 4,-3,3 4) 4,3,5

Ans. Let the other end of the diameter be (a,b,c) , then the equation of the sphere is (x-2)(x-a)+(y-3)(y-b)+(z-5)(z-c)=0

Which equals x2+y2+z2-(2+a)x-(3+b)y-(5+c)z+2a+3b+5c=0

Comparing the above equations of the sphere with the equation given and comparing the corresponding terms we get,

The required coordinates as (4,9,-3).

Ques. Four Persons independently solve a certain problem correctly with probabilities ½, ¾, ¼ and 1/8. Then the probability that the problem is solved correctly by at least one of them. [JEE Advanced 2013]

Ans. P(Problem solved by at least one of them)=1-P(Problem solved none of them)

=1-½*¼*¾*7/8

=1-21/256

=235/256

Ques. An unbiased coin is tossed. If the result is heads, a pair of unbiased dice is rolled, and the number obtained by adding the number on the two faces are noted. If the result is a tail, a card from a well-shuffled pack of 11 cards numbered 2, 3, 4…. .., 12 is picked & the number on the card is noted. What is the probability that the number noted is 7 or 8?

Ans. Let us define the events:

A : head appears.

B : Tail appears

C : 7 or 8 is noted.

We have to find the probability of C i.e. P (C)

P(C) = P(A) P (C/A) + P(B) P(C/B)

Now we calculate each of the constituents one by one P(A) = probability of appearing head=½

P(C/A) = Probability that event C takes place i.e. 7 or 8 being noted when head has already appeared. (If something has already happened then it becomes certain, i.e. now it is certain that head has appeared we have to certainly roll a pair of unbiased dice).

= 11/36 (since (6, 1) (1, 6) (5, 2) (2, 5) (3, 4) (4, 3) (6, 2) (2, 6) (3, 5) (5, 3) (4, 4) i.e. 11 favorable cases and of course 6 × 6 = 36 total number of cases)

Similarly, P(B) = 1/2

P(B/C) = 2/11 (Two favorable cases (7 and 8) and 11 total number of cases).

Hence, P(C) = ½ × 11/36 + ½ × 2/11 = 193/792 (Ans.)

Ques. Sixteen players P1, P2, ….. P16 play in a tournament. They are divided into eight pairs at random. From each pair, a winner is decided on the basis of a game played between the two players of the pair. Assuming that all the players are of equal strength, the probability that exactly one of the players P1 and P2 is among the eight winners is

(a) 4/15

(b) 5/9

(c) 3/8

(d) 8/15

Ans. Let E1 and E2 denote the event that P1 and P2 are paired or not paired together. Let A denote the event that one of the two players P1 and P2 is amongst the winners.

Since, P1 can be paired with any of the remaining 15 players, so P(E1) = 1/15

and P(E2) = 1 – P(E1) = 1 – 1/15 = 14/15

In case E1 occurs, it is certain that one of P1 and P2 will be among the winners. In case E2 occurs, the probability that exactly one of P1 and P2 is among the winners is

P[(P1 ∩ P2C) ∪ (P1C ∩ P2)] = P(P1 ∩ P2C) + P(P1C ∩ P2)

= P(P1) P(P2C) + P(P1C) P(P2)

= ½ (1 – 1/2) + (1 – 1/2)1/2

= ¼ + ¼

= ½

i.e. P(A/E1) = 1 and P(A/E2) = ½

By the total probability rule,

P(A) = P(E1). P(A/E1) + P(E2) P(A/E2)

= 1/15 (1) + 14/15(1/2)

= 8/15

Ques. In a test an examinee either guesses or copies or knows that answer to a multiple-choice question which has 4 choices. The probability that he makes a guess is 1/3 and the probability that he copies is 1/6. The probability that his answer is correct, given the copied it, is 1/8. Find the probability that he knew the answer to the question, given that he answered it correctly.

Ans.

P(g) = probability of guessing = 1/3

P(c) = probability of copying = 1/6

P(k) = probability of knowing = 1 – 1/3 – 1/6 = ½

(Since the three-event g, c and k are mutually exclusive and exhaustive)

P(w) = probability that answer is correct

P(k/w) = (P(w/k).P(k))/(P(w/c)P(c) + P(w/k)P(k) + P(w/g)P (g)) (using Bayes theorem)

= (1×1/2)/((1/8,1/6) + (1×1/2) + (1/4×1/3) )

= 24/29(Ans.)

Ques. A speaks truth 3 out of 4 times. He reported that Mohan Bagan had won the match. Find the probability that his report was correct.

Ans.

Method 1:

Let T : A speaks the truth

B : Mohan Bagan won the match

Given, P(T) = 3/4

.·. P(TC) = 1 – 1/3 = 1/4

A match can be won, drawn or loosen

.·. P(B/T) = 1/3 P(B/TC) = 2/3.

Using Bayes theorem we get

P(T/B) = (P(T).P(B/T))/(P(T).P(B/T) + P(TC)P(B/TC))

= 3/4×1/3)/(3/4×1/3 + 1/4×2/3) = (1/4)/(5/12)

=3/5

Method 2:

Let, T : The man speaks truth

A : Mohan Bagan won the match

B : He reported that Mohan Bagan has won.

P(A) = 1/3(the match may also end in a draw)

P(T) = ¾

P(B) = P(A) P(T) + P(AC) P(TC)

= 1/3×3/4 + 2/3×1/4

= ¼ + 1/6

= (3+2)/12 = 5/12

P(T/B) = (P(B/T).P(T))/(P(B)) = (1/3×3/4)/(5/12)

= 3/5 (Ans.)

JEE Main 2020 Syllabus

Mathematics: Sets, relations and functions, complex numbers and quadratic equations, matrices and determinants, permutations and combinations, mathematical signs, binomial theorems, etc.

Physics: Kinematics, Laws of Motion, Functions, Gravity, Solids and Liquids, Thermodynamics, Energy and Power, Rotating Motion etc.

Chemistry: Basic concepts of chemistry, chemical bonds and molecular structures, chemical kinetics, chemical thermodynamics, states of substances etc.

Mathematics can be easily scorable if you know the tricks and short methods for harder calculations. Remember that in a board examination marks are given for each step but in competitive exams like JEE Main, each question has 4 marks only. Now that question can take 10 steps or it can take 2 steps. That choice is the smart decision which brings out the toppers.

Keep revising your topics and maintain a small handbook for the basic formulae of trigonometry, calculus and other major sections. Mathematics is a mixture of hard work and smart work. You cannot just rely on one of them to ensure a good score. Work on your weak topics but even more on strong topics to give you an edge on them.

JEE Main Preparation Tips by Experts

Know the layout of the battle-field- Try solving as many mock papers as possible. It will provide an insight into which topics the student can solve and the sessions that need extra work. Thus the students can find their Achilles heel and turn it into armor. Students can attempt JEE Main mock tests from 9:00 a.m to 12:00 p.m and from 2:00 p.m to 5:00 p.m.

Repetition is the key to success– More you solve the question papers; proportionately your confidence will grow in facing the exams and facing it. To help the students practice, NTA has setup Test Practice centers.

Revisit and Revise- Inculcating knowledge is what a student stresses on. But what they forget is, it is equally important to be able to recall and reproduce it. Set the weekends aside to repeat the study of topics covered during the week and revise it. End of the month, evaluate how well you have studied and understood the topics covered. Hence, it will enable the student to recall well and apply the right knowledge in the exam.

Less is more- With less hand in time, it is slightly tedious to cover voluminous books with exams at the corner. Flashcards and short notes are a student’s best friend at this point. Summarizing the topics, in brief, will enable students to revise well and also cover formulas and other important topics. This handy tool will prove to be a smart choice of revision at the last stage of preparation for the exam.

Health is wealth- One key component to being kept in mind is health. In the throes of preparation, health is in a back burner. Students tend to ignore that a sound body leads to a sound mind. Eating the right food and hydrating yourself provides good fuel to the brain. Negative stress has never been any good and never will be. Practice meditation and visualizing your destination for a smooth and happy journey.

Know your enemy, know your sword– What syllabus the exam entails is tackling half the battle. Familiarize yourself with the contents of JEE Main 2020. Categorize your strengths and weakness based on the outlined course of study. Deciding how much time to be spent on a topic would be easy.

Bow and arrow– Knowing the syllabus will not suffice. Prepare yourself with the exam pattern in mind. Candidates appearing for this exam have to surf through the earlier question papers to be mentally prepared. So, knowing the syllabus and exam pattern will set you ahead in the battle.

Game Plan- The books we refer will be the game-changer. Humans are confusing souls. Too many options and our brain will go hazy. Sticking to a few reference books is the goal here. Starting with basics is the first step, and there’s only one way to go about this. It is NCERT. I can’t stress enough the importance of NCERT. NCERT is the basic template on which you can elevate by studying additional reference books.

Read through and perfect the running notes which you have jotted down. If you have a coaching center material, then it is a bonus.

Knowing topic-wise weightage will save a lot of time. It will be a great help for students to chart out their study plan and follow it through and through.

JEE Main Preparation Tips for Chemistry: Important Topics and strategies

JEE Main Chemistry is often considered as the easiest section of JEE Main examination and it happens to be the key scoring subject for JEE Main. The JEE Main Chemistry section comes with application-based questions which also require concrete theoretical knowledge from students. With the JEE Main Preparation Tips for Chemistry, students will get a grip over the basic and complex concepts to attempt such questions.

As per the experts, the level of difficulty of all the subjects is quite similar. However, last year, in JEE Main many of the candidates found Chemistry moderate but the questions on Organic Chemistry were very difficult.

JEE Main Chemistry follows the syllabus similar to what is covered in Class XI and XII Chemistry. As the scope of the syllabus is huge, candidates need to learn and retain the knowledge of a lot of equations, reactions, and formulae. This kind of rote learning makes preparation tricky but renders the subject a high-scoring one as stress is not on conceptual application but information retention and appropriate recall of the same.

Check JEE Main Syllabus for Chemistry

JEE Main Preparation Tips For Chemistry: Pointers

A few tried and tested JEE Main Preparation Tips for Chemistry from subject-matter experts are listed below for the convenience of candidates:

  1. Start with Basics – In preparation for JEE Main Chemistry, the go-to textbook are the NCERT publications. NCERT books are the most reliable ones in terms of illustrations of concepts in a lucid language. Candidates can get their basics of the subject clear with the help of the NCERT books and move on to higher level books for advanced studies.
  2. Use Limited Sources – However, it is advised that studying from too many reference books can lead to confusion and missing out on important topics. As such, candidates should limit their reference studies to the minimum and instead stress on making their own notes after each lesson so the concept gets internalized and thus easier to commit to memory.
  3. Solve Maximum Mocks – Students should also solve as many mock-papers as possible in order to score well in the exam. Consistent timed practice is the only way to ensure speed and accuracy in solving the questions in the JEE Mains exam. Attempting as many previous year’s JEE papers as possible would give candidates a real-time feel and experience of taking the test.
  4. Double Revision – Continuous revision of concepts, equations, and formulae would ensure better retention. Revision in Chemistry is required at least twice a week for all the topics/chapters that have been learned during that particular week, along with a short revision of topics which have been learned in the past.
  5. Focus of High Weightage Topics – Once the entire syllabus has been covered thoroughly, students should deploy smart prep strategy by focusing mainly on topics with higher weightage. It’s not that the entire syllabus should not be revised or practised, but the weighted topics should be focused a little more than the rest.
  6. For Physical Chemistry – The Physical Chemistry section consists of a lot of numerical problems primarily from Redox Reaction, Mole Concept and their equivalences, Solid States, Gas Theory, Thermochemistry, and Thermodynamics. It is essential to have knowledge of proper formulae and/or logic to solve questions from these topics accurately and on time.
  7. For Inorganic Chemistry – Inorganic Chemistry’s most scoring topic is Chemical Bonding and Periodic Table and maximum questions from this unit are in the context of bond formation, bond breaking, and periodicity, S-Block, F-Block, D and F-Block elements etc.
  8. For Organic Chemistry – Organic Chemistry is mostly concept based. Candidates would be able to score really good marks if they focus on carbonyl groups reactions and their mechanism. Physical properties of organic groups, the polarization of carbonyl compounds, the hydrogen group, and carbon groups are the most frequently asked questions in the JEE Main Examination.

JEE Main Preparation Tips for Physics: Important topics and Strategies

JEE Main Preparation Tips for Physics: Joint Entrance Examination (JEE) is one of the most popular and sought-after engineering entrance exams in India and every year lakhs of candidates appear in the entrance to seek admissions into top engineering institutes. Physics subject is considered as one of the toughest subjects and it happens to be the key subject for JEE Main. The Physics section comes with application-based questions which are easy to solve but difficult to interpret. Students need to have a grip over the basic concepts to attempt such questions.

As per experts, the level of difficulty of Physics is similar to the other two subjects and is moderate to easy. However, last year, JEE Main was relatively tough with Physics being the toughest section to crack. Further, past trends have reflected that Physics has always been tricky and on the tougher side. Here, it becomes important for candidates to buckle up and kickstart their preparations, as Physics is all set to give you a tough time.

Study Approach for JEE Main Physics Preparation

Strengthening Basics

To start with, it’s important for students to strengthen their fundamentals and basic concepts. They must complete the prescribed JEE Main Syllabus and there is no shortcut to this. Even a single question can make a difference to your JEE scores and percentile with a marginal difference. For JEE Main, students must refer to NCERT Class XI and XII Physics books to get a grasp of concepts to a basic level. Further, they must delve deep into each topic by referring to other books.

Topic-wise Preparation

Next step towards preparation should be the analysis of previous years’ JEE Main question papers. Know the topics covered and weightage given to each topic in terms of the number of questions and the level of difficulty. Based on the importance of each topic, plan your preparation schedule. Hereunder, we have categorized major topics based on their importance as per previous years’ trends.

Boards or JEE Main?

There is no need to worry about fetching out extra time along with class 12 boards as JEE Main and board exam preparation can be clubbed together due to similarity in the syllabus. The only difference is while attempting a board examination, students must be prepared for a subjective paper and while attempting JEE Main, the main focus should be on the speed with accuracy.

How To Prepare For JEE Main Physics?

Various students have the varying interest and therefore varying knowledge of Physics accordingly. Physics section of JEE Main and JEE Advanced is a scoring section similar to Mathematics as it requires a logical approach along with calculations. A lot of students find Physics easier compared to Chemistry due to a large number of topics in Chemistry. Given below are some tips which will help students know exactly what they are lacking in their preparation for JEE Main Physics.

  • Short notes of formulas: It is imperative that you create short notes for formulas while studying any chapter of Physics. These short notes of formulae will help you revise easily during the last few days.
  • Read the Question thoroughly: It is of utmost importance that you have understood the question properly before attempting it. Sometimes, it is possible that the question requires a combined approach of two or more topics, because of which it is difficult to understand.
  • Accuracy is the key: While solving mock tests or practice papers, students generally practice speed but do not work on accuracy. Accuracy is gained by solving the questions correctly. Higher accuracy is important than higher speed.
  • Previous Year Question Papers and Mock Tests: The examination mode has changed and it requires the student to sit in front of a bright screen for more than 3 hours continuously. Mocks Tests for JEE Main will help you get used to this. Practice previous year question papers with a classic approach to end distractions from mobile phones or laptops.
  • Revision every week: Howsoever easy it might seem, revising a full subject during the last few weeks is just impossible. To make sure the topics are within your mind, revision is required every week. Along with this, difficult questions must be marked to attempt later on.
  • Study 3 hours, Analyse 3 hours: It is important to solve at least 1 full mock of 3 hours every two or three days once the whole syllabus is complete. But what’s even more important is analysing that particular mock test and the performance. Working on the right approach, weak and strong topics will help boost the scores in future.

Benefits of Solving JEE Main Previous Year Question Papers

Resources from previous year question papers of JEE Main will be beneficial in many ways to each and every student. The main aim should be to decipher what the trend will be for the upcoming examination. Read below to how the JEE Main Previous Year Question Papers can be beneficial for you.

  • Understanding Question Pattern – While the exam pattern is said to be important, what’s even more important is the question pattern. A question in a board examination requires subjective knowledge. But for JEE Main, it might require conceptual knowledge of more than two chapters combined.
  • Repeating Questions – It does not go unnoticed, but students might forget that there are certain questions which repeat almost every single year. Previous year question papers can help in practising such questions. Usually there is a numerical change or a combination of two other topics in separate years.
  • Full Revision – Revision is not a difficult task if students have a clear approach of solving moderate to complex problems during the last few weeks. But it is obvious that questions from books might already be solved. In such a case, previous year question papers will be helpful.
  • Less Distractions – Students have a habit of using pen and paper while solving problems. While exam mode has completely changed to computer-based, rough sheets will still be provided for solving numerical questions. Previous Year Question Papers bring back the classic approach which prevents random distractions that a smartphone or PC might have.

JEE Main Mock Tests vs JEE Main Previous Year Question Papers

A lot of students are confused between JEE Main Mock Tests and JEE Main Previous Year Question Papers. Due to the confusion, they are unable to figure which one of these two would be the right option to enhance the preparation for the examination.

In that case, first, they need to understand the meaning of the Mock Test. A mock test is nothing but a copy or a simulation of the actual examination. When a student is attempting a mock test, he/she is practically attempting a simulation of the examination. It ultimately helps students in getting adapted towards the examination environment as they might be attempting the exam for the first time.

Now, usually, a JEE Main Mock Test is designed from scratch. This means all the questions are usually new and only a few questions are taken from old question papers. But NTA, the official agency for conducting JEE Main, has provided JEE Main Mock Tests of JEE Main Previous Year Question Papers. Students can attempt the previous year question papers of the year 2019, 2018 and 2017 using the mock tests provided on the official website of NTA.

Platforms providing question papers as mock tests

Other than this, a lot of other educational websites and institutions also provide JEE Main Previous Year Question Papers as Mock Tests such as-

  1. Resonance – Resonance is one of the top educational institutions in India for preparation of JEE and NEET examinations. JEE Main Previous Year Questions Papers, as well as Answer Keys, are available on the official website of Resonance. Students will find question papers from 2013 to 2019 which are more than sufficient.
  2. BYJU’S – BYJU’s is a top e-learning platform for school kids and teenagers. Once a student has registered, they can download question papers of 2019 to 2014 along with answer keys for various sets of the question papers for JEE Main.
  3. JEE Main Guru JEE Main Guru has a large database of combined study notes and previous year question papers of JEE Main and Advanced from various other institutes such as Allen, Aakash etc. The major content is available in PDF form which can be downloaded and used offline.
  4. Vedantu – This e-learning platform is famous for its free video lectures as well as free mock tests. Students can attempt a large number of tests and also watch analysis videos of those tests to figure out the errors they might have made during the attempt.

There are many other educational platforms available for solving mock tests based on JEE Main previous year question papers. You can try whichever platform suits you the best.

JEE Main Test Practice Paper Centers

This year, to benefit the students and prepare them well for the entrance tests, National Testing Agency (NTA) has established a network of more than 3000 Test Practice Centres spread all over India. Students can now go and practice and train themselves before the examination for the “Computer Based Test (CBT)” mode of examinations.

The experienced, qualified and professional Nodal officer and staff available at the Test Practice Center will help and motivate the students to clear their doubts and solve problems and to make them familiar with the CBT mode of examinations.

Students can only visit the practice test centers on the specific day and schedule which is given below:

Day Timings
On working day Monday to Friday 2.00 p.m. – 4:00 p.m.
On Saturday, Sunday and holidays 10.00 a.m. – 4:00 p.m.

The types of questions and topics which are asked in the exam differ each year. However, the JEE Main previous year question papers are helpful for the students in knowing more about the exam pattern and the kind of questions that are asked in the exam. According to the students who gave JEE Main in 2019, the questions asked in the exam were moderately difficult in terms of difficulty level. The Physics section was the most difficult section and more questions came from the analytical section which needed long calculations and assumptions. The students reviewed that Chemistry was the easiest section among all the sections in the exam.

Things To Remember While Studying Chemistry

JEE Main Chemistry is often called out as a scoring section for most of the JEE aspirants. This is because every year, the question paper for Chemistry has easy to moderate questions on basic concepts. Questions also take less time to solve as they require theoretical knowledge rather than any calculations.

JEE Main Chemistry syllabus is more about a planned approach rather than direct conceptual applications. The students must be thorough with all the formulas, named reactions, chemical equations, and periodic table trends as all these concepts constitute a major portion of JEE Main Chemistry syllabus. There could be a large chunk of direct and indirect questions from the above-mentioned concepts.

But it is also important to note that just memorizing the theory and formulas will not always work for a JEE Main aspirant in developing the problem-solving skills. At the end, there must be the knowledge of what logic works behind a particular concept.
