The JEE Mains 2026 syllabus is a wide syllabus in Physics, Chemistry, and Mathematics. Not all topics are of equal importance in the exam. When candidates understand the weightage of topics, they can check which chapters are consistently asked and help in getting more marks. This lets them prioritize those topics when preparing, which ensures the maximum return on effort and time invested.
Since candidates usually have limited time for preparation, knowing the weightage helps in creating a proper study plan. Rather than spending similar time on all chapters, candidates can divide more hours to high-weightage topics, which gives less time to low-weightage topics. This proper allocation of time is useful in completing the syllabus without feeling stressed.
Those topics that have the most weightage are responsible for achieving a greater portion of the exam’s total marks. If you give time as well as attention to these topics, you can improve the chances of scoring better even in times when you are not able to study every single topic. For example, if you master high-weightage chapters like Coordinate Geometry or Organic Chemistry, you can achieve a strong possibility of getting a higher score.

Frequently Asked Questions (FAQs)
The highest weightage chapters in JEE Main for Physics, Chemistry, and Mathematics are as follows
Chemistry- Coordination Chemistry, Chemical Thermodynamics, and some basic concepts of chemistry, and so on.
Physics- Optics, Electrostatics, and Properties of Solid and Liquid, etc.
Maths- Co-ordinate geometry, Integral Calculas and Limit, continuity and differentiability, and so on.
JEE Main is held for 300 marks. Marks above 200+ are considered good marks and will help to secure the 95-99 percentile. Whereas, 120 is considered to be an average mark in JEE Main, with a percentile ranging between 95-96%.
When you know what topics carry more marks, you can divide the study hours properly. So, it helps in studying important topics first and the rest later.
Must have passed or be appearing in Class 12 (or equivalent) in 2024, 2025, or 2026. No age limit, but the candidate must meet institute-specific age limits if applying through JEE scores.
Yes. JEE syllabus is primarily based on NCERT Class 11 & 12 topics. However, some additional concepts may appear in JEE Advanced.
The results generally get released after 1 week of each session.
Yes, as the exam questions can be of any kind. If you study only high-weightage topics, you may ignore the easy questions from smaller chapters. So, study everything but give more time to high-weightage topics.
Not really. The division modifies in some amount each year, but some topics like Coordinate Geometry, Organic Chemistry, Thermodynamics, and Electrostatics are observed to appear regularly.

Hello murali
No, your son is not eligible for OBC NCL for IIT JEE because you fall in the "creamy layer" occupational category, regardless of your current employment status or family income. Students whose family income is less than Rs. 8 lakhs annually and they are not belong to the "creamy layer".
Note -
Thank You
Hello,
You can fill the JEE Main form even if you are a private candidate
Write the
name of the school/board from where you are appearing as a private candidate
.
If your Class 12 admit card or registration slip shows a school/centre name, use that exactly.
If your board lists you as a “Private Candidate” under the board name , then write:
CBSE – Private Candidate
(or your board name – Private Candidate)
Use the pin code of the examination centre/school mentioned on your Class 12 private candidate admit card or registration details.
If your board does not give any school address and only shows the regional office address, then use the regional office address pin code given by your board.
Hope it helps !
Hello Aspirant
You should not leave the OBC-NCL certificate ID blank in the JEE Main form it can create problems later.
NTA wants the certificate details while filling the form, not just at counselling. If you can, apply for the OBC-NCL certificate immediately so you get the ID on time.
If you fail to submit the certificate during counselling, your category will shift to General. It’s safer to enter OBC-NCL only if you’re sure you’ll get the certificate before counselling.
Hope it will help you
Hello,
No, X-rays are not deleted for the JEE 2026 exams. X-rays are part of the electromagnetic spectrum, a topic that remains in the syllabus for both JEE Main and JEE Advanced. Here in this article you will find more about the JEE Main syllabus.
I hope it will clear your query!!
