JEE Main 2025 January 29 Shift Question Paper -Difficulty Level

As per the observation of the previous days' analysis, the difficulty level of the JEE Main question paper is overall moderate level. In Chemistry, students would do better with NCERT-only, for all chemistry questions are right out of the NCERT. For Physics, they must practice formula questions, and Mathematics is quite lengthy and time-consuming.

You can check the JEE Main 2025 question paper analysis according to the feedback we got for the last few days’ shifts. Here you can check it:

1. Mathematics:

• The paper was manageable for those who had prepared well. The topics covered were a mix of easy questions and moderate-level problems.

• Difficult questions were fewer, but those who prepared thoroughly could still tackle them effectively.

• Topics like Quadratic Equations, Sequences and Series, and Matrices were frequently asked.

• Complex numbers and the Binomial Theorem also had a few questions.

• Differentiation and Integration were prominent, with several questions on the Application of Derivatives and Definite Integrals.

• Questions on Straight Lines and Conic Sections (especially Circles and Parabolas) were commons

• Trigonometric identities and equations were included, though not extensively.

2. Physics:

• Most questions were easy to moderate, with only a small portion being tough.

• Physics was manageable for most students, especially if they had a solid grasp of basic concepts. Moderate-level questions were expected, and easier questions made the section more approachable.

• Topics like Newton's Laws of Motion, Work, Energy & Power, and Rotational Motion appeared frequently.

• Gravitation and Kinetic Theory of Gases were also important areas.

• Coulomb’s Law, Capacitance, Current Electricity, and Magnetic Effects of Current were commonly tested.

• Electromagnetic Induction had a couple of questions as well.

• Photoelectric Effect, Atomic Structure, and Radioactivity were recurring topics in the exam.

3. Chemistry:

• Chemistry was slightly more challenging compared to Physics and Mathematics.

• The difficult portion was notable, requiring thorough preparation, especially in areas like Physical Chemistry and Inorganic Chemistry. Students should focus more on Chemistry in future shifts as it poses a challenge for many candidates.

• Topics like Chemical Kinetics, Thermodynamics, and Mole Concepts were highly featured.

• Equilibrium and Electrochemistry appeared in moderate questions.

• Reaction Mechanisms, especially Aromatic Substitution and Functional Groups, were frequently tested.

• Hydrocarbons and Polymers appeared as well.
