In the Kinematics chapter of Physics, the National Testing Agency has made a few slight changes. Concepts such as scalars and vectors were also excluded from the exam curriculum of JEE Main 2025. According to the JEE Syllabus 2025 official Website, Paper 1 includes Class XI & XII in Physics, Chemistry, and Mathematics. JEE Mains 2025 Syllabus of Paper 2A is Mathematics, General Aptitude, and Drawing for the B.Arch, while for Papers 2B is Mathematics, General Aptitude, and Planning for B.Plan.
Here’s a brief look into the JEE Main Syllabus 2025 along with key data insights and important topics based on past trends:
- Subject-wise Composition: Approximately each subject contains about 20 to 25 chapters. This meant equal weightage on each subject therefore candidates should prepare for all three subjects equally.
- Important Topics:
- Physics: Mechanics, Thermodynamics, Electricity & Magnetism, and Modern Physics
- Chemistry: Organic reactions, Physical Chemistry concepts like Thermodynamics and Equilibrium, and Inorganic Chemistry (p-block, d & f block elements)
- Mathematics: Calculus, Algebra, Coordinate Geometry, and Trigonometry
- Difficulty Levels: About 35-40% of questions are moderately difficult, 30-35% easy, and the rest challenging.
In 2024, the national average score was around 70-75 out of 300. Approximately 1-2% of candidates scored above the 90 percentile, highlighting the need for thorough preparation.

- In Physics areas such as Mechanics, Electricity and Magnetism constitute major areas while in Mathematics Calculus and Algebra play a very big role.
- Chemistry has three main sections, namely Physical, Organic and Inorganic; courses offered here tend to focus majorly on Organic Chemistry and Chemical Bonding.

Practicing as many mock tests as possible will help you get used to the exam format and also familiarise you with the questions asked in the exam, practise mental maths can speed up calculation process during the exam, meditation or deep breathing and complete rest the night before exam will help manage stress and remain calm during the exam.
Is there any change in the syllabus of JEE Mains for 2024?
Yes, there have been modifications to the JEE Mains 2024 syllabus. Specifically, some sections related to mathematics, chemistry, and physics have been removed.
Mathematics is often considered as the most challenging subject in JEE due to its concept-based and application-oriented questions which requires deep understanding of concepts. However, students can overcome this by understanding the vast syllabus of the subject and dividing it into smaller topics and focusing more on the topics in which they struggle. Brushing up and being profiecient in basic and fundamental concepts is crucial. And most importantly, regualar practice of questions whether from mock papers or previous year question papers will help the students massively.
A 250+ score is considered a good score in JEE Mainas it will fetch you the 99 percentile, which is essential to get admission into the top engineering colleges like IIT, NIT, IIIT, etc. All subjects are important for getting a good score, however, Chemistry is the most scoring subject with the average score being more than 35 marks; Mathematics on the other hand is the most difficult to score off averaging a little over 25.

How important are the Board Exams for JEE Mains accepting colleges? Should I focus on just JEE or on Board Exams? How to manage time accordingly?
Both Board exams and JEE Mains are equally important. To be eligible for admission through JEE, candidates must secure a minimum of 75% marks (65% marks for SC/ ST) in their respective Class 12 Board exams. Create a proper time table and focus on the common subjects and chapters in both Board exam and JEE Mains. Allot time for the practice of mock test and previou year papers of both Boards and JEE Main exam. Dedicate your full preparation to Board exams two months prior to its commencement. Once the Board exams are over, shift the complete focus to JEE preparation and daily solve pratice tests and attend mock exams.
