Top 20 Percentile Cutoff Marks for Class XII Exam

JEE Main 2019 is underway with commencement of registration for the January session. Most of the students are worried about filling all the details carefully in JEE Main Application Form and ensuring that feel the desired eligibility criteria to avoid rejection. A lot of candidates search for top percentile cutoff marks in JEE Main.

JoSAA is responsible for releasing the top 20 percentile for JEE Main and JEE Advanced. The top 20 percentile cut off marks is released separately for IITs and other institutes (NITs, IIITs and CFTIs) on the official site, jossa.nic.in. Although the top 20 percentile is released after the result declaration, candidates must be aware about the previous year trends.

What is the top 20 percentile?

Each year as many as a million of students appear for JEE and NIT entrance examinations with the view of gaining admission in top engineering institutes. Even though the marks secured in Class 12th is no longer considered for JEE Main Rank Calculation, yet it is a determining factor for admission to IITs, NITs, IIITs and CFTIs. However, not all the state education boards release marks in the form of percentage. Therefore, the organizing authority will also consider candidates failling in the top 20 percentile while determining their eligibility.

Top 20 Percentile for JEE main

Eligibility Criteria

In order to secure a place in JEE or NITs, candidates will have to fulfill the following requirements:

  • The minimum eligibility is to secure 75% for General Category. For reserved category belonging to SC/ ST/ PwD, the minimum eligibility is scoring 65% in the class 12 examination.


  • They must fall in the top 20 percentile category in class 12 of their respective boards or qualifying examination.
  • Even though a candidate fails to secure 75% in their class 12th, they still hold opportunity for appearing in the entrance examinations on the basis of top 20 percentile marks.

How are class 12th marks calculated for admission to IITs and NITs

The calculation of score will be as follows:

  • The score of candidates will be calculated for any 5 subjects which in total will be calculated out of 500. These five subjects will include Physics, Chemistry, and Mathematics as compulsory subjects out of the five. The other two include one language subject and one other subject (expect from the four already selected). In this manner, the total secured in the five subjects with aggregate marks 500 will be taken into account.
  • In case, a candidate has taken two language subjects, then the subject with a higher score will be considered.
  • If the marks of any subject are not awarded out of 100, then in such cases, the score will be scaled to make it out of 100. For example – if a candidate secures 50 out of 80, then the calculation of score will be as follows: (65/80)*100 = 81%
  • If a candidate has appeared for Class 12th examination in the year 2016 and again reappears in 2017 for improvement in any one or two subjects, then the marks secured in 2016 will be considered and not that of 2017.
  • However, in case a candidate had appeared in 2016, yet reappears for improvement in all 5 exams conducted in 2017, in that case, the scores of the year in which the candidate has score more marks will be considered.

Difference Between Percentage and Percentile

Often candidates get obscured of the difference between a percentage score and percentile. However, both the terms are completely different from one another. A percentage score is marks obtained by a candidate from the aggregate of 100. On the other hand, a percentile is a term used to define the percentage a candidate secures below particular marks.

Example – Suppose a candidate has secured 85 percent marks. This is the marks secured out of 100, wherein he/she has scored 85. If the total is 200 it will be 170 and so on. However, if a candidate mentions he/she has scored 85 percentile, that would mean 85 percent of all other candidates who have appeared for the examination have score fewer marks than the candidate with 85 percentile.

They are also hopeful that this change will be advantageous for candidates in following ways:-

  • Keeping track of Unattempted Questions- Candidates can easily revisit the questions they are doubtful of or haven’t answered. It is advisable for that candidates first solve the easier questions then revisit the questions they were in doubt of.
  • Change in Exam Date and slot – As the exams will be held in multiple slots, candidates can choose their time slot and date as per their convenience
  • No scope of Cheating – Unique questions will provide a fair chance to all the candidates as the software will pick different questions for all candidates and leaving no scope of cheating for the candidates
  • Introducing different levels of questions – The difficulty level of the questions in the exam will be increased on the basis of candidate’s past answers.
  • Introducing Computer Adaptive Testing – The answer keys will also be released using Artificial intelligence techniques to ensure free work in computing the result

NTA to set Unique Question papers for JEE Main and NEET Aspirants

Currently the agency is performing psychometric analysis of past years’ question papers including the MCQ questions. They are also checking the impact of introducing MCQ questions. These distractors will help in checking candidate’s overall knowledge of the subject. One of the disadvantage of using software system is that candidates will be at the mercy of the software which will pick the questions on random basis. The answer keys will also be released by Artificial intelligence system.

Latest Alerts:

Till 2017 CBSE or Central Board of Secondary Education used to conduct these exams. In order to reduce the burden of CBSE and smooth conduction of exams, HRD ministry introduced NTA. The new authority will conduct these exams twice a year. JEE Main 2019 is scheduled to take place in January and April 2019. The agency is expected to test around 1.5 crore candidates at National level.

According to HRD officials, a number of tests and experiments will be tried such as psychometric data analysis of data, psychometric analysis for training the item writers and web based, etc to ensure there are no errors in question papers and answer keys.

  • NCERT textbooks are reliable for understanding preliminary concepts. Move to other books only after you have solved NCERT books.
  • You should brush up the basics to get a grip on the fundamental topics.
  • Make a schedule, and try to stick to it.
  • Choose the right set of books.
  • Practice is the key to Mathematics, so you must practise as much as you can from the past year question booklets and sample papers.
  • Spend more time on solve problem instead of reading solutions/theories/formulae
  • The more you solve, the more tricks and methods, you will find to solve the questions.
  • Formulae are very important in mathematics. Creating a table that topics and formulas from all the chapters can prove very useful. 
  • Solving two to three model questions papers will help you a lot as it will help you manage your time better and get your rhythm going.
  • Special attention must be given to topics under calculus and algebra. These two are crucial topics and must be practiced regularly.
