JEE Main 2025 January 22 Shift 1 Question Paper analysis

This is a detailed analysis based on the responses we got from the students. Lets see in detail:

1. Mathematics: Mathematics was overall moderate. It was 40% easy, 40% moderate and 20% difficult as per the responses we got. So, we can say that it was manageable for those who have prepared for the exam well.

2. Physics: Physics was also on the moderate side. It has 50% easy, 33% moderate and 17% difficult questions as per our analysis. Most of the questions were easy to moderate. There are chances of having the same level of questions in the next question paper.

3. Chemistry: Chemistry was moderate to difficult as per the analysis. It was 37% easy, 33% moderate and 30% difficult. The next batch should be more prepared for the exam especially for chemistry and Maths.

JEE Main Previous Years Question Paper

Previous year question papers are always helpful in the preparation of JEE Main. You can refer to and practice previous year's question papers so that you can get more clarity on how the JEE Mains 2025 question paper can be. Check here:

JEE Main Previous Year Analysis

Here is a detailed analysis of the JEE Main previous year analysis:

JEE Main previous year analysis for Mathematics Section

1. Calculus:

   • Differentiation and Integration: Calculus continued to dominate the Mathematics section in 2024. Questions on differentiation (maxima and minima, tangents, rate of change) and integration (definite integrals, areas under curves) were commonly asked. In addition, application-based questions from topics like differential equations were seen.

   • Definite Integrals and Area under Curves: These topics were frequently tested, especially in Application of Integrals questions, where candidates had to find the area between curves.

2. Algebra:

   • Quadratic Equations: Quadratic equations with real and complex roots, discriminants, and their geometric interpretation were featured.

   • Progressions: Questions on Arithmetic Progressions (AP) and Geometric Progressions (GP), particularly related to sum formulas and properties, were commonly found.

   • Matrices and Determinants: Problems involving matrix operations, inverse of matrices, and determinants were regularly included.

3. Coordinate Geometry:

   • Circles, Ellipses, and Hyperbolas: These topics were tested with a mix of direct and application-based questions. Questions typically required the use of equations of conics and related geometrical properties (e.g., tangents, distance from point to conic).

   • Straight Lines and Parabolas: In addition to conics, questions based on the properties of parabolas and straight lines (e.g., slope, equation, distance between points) were present.

4. Vectors and 3D Geometry:

   • Topics like vectors, dot and cross products, and 3D geometry questions involving the equation of planes, lines, and distance from a point to a plane were asked in 2024.

   • Questions on atomic structure, photoelectric effect, and nuclear physics were prominent in 2024. Problems focused on Bohr’s model of the atom, half-life, and nuclear decay.

   • The dual nature of matter and de Broglie’s hypothesis also appeared in a few questions.

4. Thermodynamics:

   • Laws of Thermodynamics, heat transfer, and the Carnot engine were the focus. Problems with entropy, internal energy, and specific heat were tested.

JEE previous year analysis for Chemistry Section

1. Organic Chemistry:

   • Reaction Mechanisms: Organic chemistry dominated the Chemistry section with a strong emphasis on reaction mechanisms. Topics like SN1/SN2 reactions, electrophilic and nucleophilic substitution reactions, and aromatic substitution were prevalent.

   • Hydrocarbons and Alcohols: These topics were tested through reactions, naming reactions, and properties of different functional groups.

   • Aromatic Compounds: Reactions and mechanisms involving benzene derivatives and their electrophilic substitution were commonly tested.

2. Physical Chemistry:
