The physics section was the toughest. Candidates found numerical questions more difficult and lengthy. There were most questions are from thermodynamics, resistance, and fluids, etc. A few questions were from optics. Aspirants said that the overall difficulty of the physics section was moderate. With a response of these kinds, you must not leave any section as the question distribution is quite unpredictable.

Section Questions
Mechanics 5
Current Electricity and EMI 4
Heat and Thermodynamics 6
Optics and Modern Physics 3
Fluids & Resistance 7

JEE Main Paper 1 Analysis: Mathematics

In Mathematics, there were many questions from Trigonometry and Calculus. It was based more on the applied aspect of mathematics. Most aspirants found it difficult to complete the section because it was lengthy as well as tricky. The question distribution was as follows-

Section Questions
Algebra 6
Calculus 8
Coordinate Geometry 4
Trigonometry 7

Overall, it can be said that students found the exam moderate. Physics was the toughest section which was compensated by Chemistry asking direct questions. Considering the reviews from aspirants and experts, the expected cut off for the exam will be between 72-77 marks.

According to JEE Main paper analysis, Physics was the most difficult section and had a lot of questions from Mechanics and Electrodynamics. The questions were tricky which needed a thorough grasp over important physics derivation to solve them.

The Chemistry section was direct and the easiest among all. There were equal questions from Physical, Organic and Inorganic Chemistry. It was the scoring section for the aspirants. So, for the upcoming session, you cannot compromise on either section. However, as per 1 aspirant, there was a glitch in 1 of the questions where there were 2 same options in 1 question.

Here are some JEE Main Sample Papers
