Last updated on September 2nd, 2020 at 07:12 pm

Its Day 2 for JEE Main and the first shift of B.E / B.Tech paper has been concluded. The exam is conducted for admissions to NITs, IIITs and GFTIs. Paper 2 (B.Arch) and Paper 3 (B.Planning) of JEE Main 2020 was conducted yesterday.

According to students, the COVID-19 social distancing and sanitization guidelines were followed outside and inside the exam centres. Students were put through thermal screening, provided fresh surgical masks and also asked to sanitize at all entry checkpoints inside the examination halls.

Students’ Reaction For JEE Main Paper 1 (B.E / B.Tech)

As per the majority of students, JEE Main Paper 1 of first shift was of easy to moderate difficulty level.

  • The Physics section was a bit tough than expected with lengthy questions.
  • Numerical Value Questions were easier in Mathematics.
  • Chemistry had more theoretical questions instead of numericals.
  • Majority of questions were from 12th Syllabus only.

According to the experts from Aakash Institute, the exam in 1st shift was moderate. The mathematics section was easier than January 2020 session. Physics was the toughest section of all and Chemistry was also easy and quick to solve.

SOP Not Followed After Exiting Exam Halls

A few students have tweeted about no guidelines being followed once the exam has concluded. Students seem to be rushing without any social distancing to leave from exam halls.

The JEE Main Paper 2 is being conducted by NTA in 660 centres in India and 8 centres abroad. First shift is conducted from 9 AM to 12 PM and second shift will start from 3 PM to 6 PM.

For the April / September session, 841188 students have registered for the B.E / B.Tech paper. Almost 85,000 students will appear today in the first shift of JEE Main.

Paper Analysis by Students

Students can check the JEE Main Paper Analysis and first reactions from students of various states below.


Candidates were happy about the COVID-19 Safety Guidelines being followed at the exam centres. JEE Main B.E/B.Tech paper’s difficulty level was moderate.

A candidate named Rajan Singh said, “The exam was moderate to difficult for me. I got nervous when the computer suddenly shut down for me. I lost around 5 minutes there.”


One of the candidates at JEE centre of Chandigarh, Chirag Bhatia, said that due to postponement he got much more time to prepare his weak topics in Chemistry. Many students reported that Chemistry was easiest of all sections. Physics was the toughest.

A student named Tanish said that NTA’s Sample Papers for JEE Main were much tougher than exam held in 1st Shift today.


A total of 16 centres in 9 cities were allocated for JEE Main in Haryana. Students were reporting to the exam centres at staggered time slots mentioned in their Admit Cards.

Sumit Kumar from Hisar said that he was happy the exams were not postponed further. Now, he is free of the anxiousness due to exams. He added, “Government have saved us the entire academic year by conducting the exams on time. Students should not be worried about safety protocols at the exam centres.


Divya Rani, a JEE Main candidate, took the exam from Patliputra centre. She said, “Physics was lengthy and time-consuming. Chemistry section was easiest as major questions were theoretical and same as NCERT books. Maths was also easy compared to expectations of major students.”

Overall, students said that the exam was much easier than the January Session of JEE Main 2020.

What Items To Carry At Exam Halls?

Candidates can carry only the following items inside exam halls. Facility to store bags has been provided to candidates as per JEE Main COVID-19 Safety Protocols released by NTA.

  1. JEE Main 2020 Admit Card (Duly filled with signed self-declaration)
