The chemistry section in paper 1 was the easiest but a lengthy section as per most candidates. There were many direct questions from NCERT books. It was the scoring section for which you must have your concepts clear. If aspirants practiced previous year question papers well, they can score good marks in Chemistry.

Here is the section-wise question distribution-

Section Questions
Physical Chemistry 9
Organic Chemistry 9
Inorganic Chemistry 12

JEE Main Paper 1 Analysis: Physics

Physics section had an uneven distribution among the various topics. According to aspirants so far, Physics is the toughest section to attempt. There were no questions from ‘Fluids’ and only 2 questions were asked from ‘thermodynamics’. Majority of questions were from ‘mechanics’ part. With a response of this kinds, you must not leave any section as the question distribution is quite unpredictable.

Section Questions
Mechanics 8
Current Electricity and EMI 7
Heat and Thermodynamics 6
Optics and Modern Physics 5
Electrostatics and Magnetism 4

JEE Main Paper 1 Analysis: Mathematics

In Mathematics, there were many questions from conic section. It was based more on 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 10
Calculus 8
Coordinate Geometry 6
Trigonometry 6

With both sessions over for day 1 of JEE Main, it can be said that students found the exam moderately tough. If Mathematics was a tough and lengthy section, Chemistry compensated it by asking direct questions. Considering the reviews from aspirants and experts, expected cut off for the exam will be between 72-77 marks.

JEE Main 2018 Paper 1 Analysis

There were many questions from the previous year question papers. Hence, it is very necessary that you practice previous year question papers.

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 definitely needed a thorough grasp over important physics derivation to solve them.

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
