JEE Main 2025 April 2 Analysis and Student Reaction (Shift 1 OUT)

Here are the highlights of the first reactions of the candidates who appeared in the first shift exam on 1st April 2025 to help the candidates appearing in the upcoming days to get an idea of the level of the paper.

The question paper was moderately difficult as per the students who appeared in the exam.
Maths has more conceptual questions and less calculation questions, that is why the question paper was not time consuming.
The Chemistry section had an average of 7-8 questions from inorganic, organic and physical chemistry. Some questions from Chemistry were difficult but solvable.
The Physics section was the easiest among all the sections. It was the least time consuming section.

JEE Main Session 2 Shift 1 Topics Asked Questions

Topics asked in Maths: Conic section, Vector 3D, Permutation and Combination, Binomials, Circle, Logarithms, Quadratic, Sequence and Series

Topics asked in Physics: Units and Dimension, Pressure, Rotation, Fluid Mechanics, Thermodynamics

Topics asked in Chemistry: Physical chemistry was asked more, Organic was less, and Inorganic also had more weightage.

As per the student, frisking in the exam centre was very strict. Candidates are not allowed to wear shoes in the exam hall, and also no candidate is allowed to enter the exam centre after the gate closing time.

JEE main 2025 April 2 Shift 1: Maths easier than January Session, Physics bit Tricky
