Competition in JEE Mains is increasing every year. According to the National Testing Agency (NTA), approximately 8.6 lakh candidates appeared in the first session of JEE Mains 2023. Because of the cut-throat competition among aspirants, it is very important to have a clear idea of the JEE Main chapterwise weightage.
The Mains exam is challenging and hence requires a lot of practice and dedication. An aspirant has to dedicate time to complete the syllabus. Along with dedication and practice, a candidate should have access to proper resources like books, study materials, online videos, mock tests, and expert guidance.
Having proper knowledge of the JEE Main syllabus and the weightage of all chapters is very crucial. This will help the candidates focus on and prioritize the important topics. This will empower you to prioritize topics based on your expertise.
However, if you want to get a good grade, skipping a topic is a bad idea. Therefore, we recommend a JEE aspirant go through the syllabus and chapter-wise weightage before starting the preparation.
Read this article to understand the entire JEE Main 2023 syllabus, along with its weightage.
JEE Physics Syllabus with Weightage
Physics is a tough and interesting subject. It contains both theoretical concepts and numerical problems. Candidates must have a good understanding of the concepts and theorems.
Topics like magnetism, electricity, and thermodynamics are very important, as they contain the maximum weightage. One of the best books for physics is Concepts of Physics by H.C. Verma, Vol 1 and 2.
Pro Tip:
- Electrostatics is a very lengthy but easy subject. Every year, there are three to four questions on this topic.
- Current electricity is a short topic but scoring as well. Every year, questions on colour coding, Ohm’s Law, and other topics are common in JEE Main.
- Electromagnetic induction and alternating current are also easy topics for JEE Main.
- Semiconductor & Electronic Devices, Communications, Units & Dimensions, Error Measurement (Relative and Absolute), Instruments. These are short and scoreable topics. In JEE Main, usually you can find one question from each of these topics. So, don’t think of skipping these topics. You can easily fetch 16 to 20 marks from these.

JEE Main Maths Syllabus with Weightage
The JEE aspirants consider mathematics a tough subject. The math syllabus is comparatively lengthier than physics and chemistry. If answered properly, this subject can help you fetch full marks.
Therefore, it is very important for candidates to have clear mathematical concepts. The syllabus for math is the same for B.E/B. Tech, B.Arch, and B.Planning.
We recommend R.S Agarwal and NCERT Mathematics books for your JEE preparation.
Pro Tip:
- Vector algebra, derivatives, limit and continuity, matrices, and determinants are easy-to-score topics.
- Coordinate geometry, 3-D geometry, integral calculus, matrices and determinants, integration, and derivations are important topics.
