How Chapter-wise Weightage Helps in JEE Main Preparation?
Clever Study Preparation: Understanding the chapter-wise weightage allows you to concentrate on topics with higher marks in your exam. You can thus wisely allocate your study time to important topics instead of extending the time equally to every chapter. This will allow you to prepare in an organized manner and with a sense of purpose.
Effective Time Management: With weightage in hand, you can wisely plan your daily or weekly study schedule. You can give time for the high weightage chapters and quickly revise the less important chapters along with the previous one. This way, you can cover the curriculum promptly without any hassle.
Enhanced Revision Strategy: While doing revision using weightage, you understand which chapters require extra care. You can focus and study accordingly with important questions of the chapters. This systematic revision ultimately leads to better accuracy with maximum syllabus covered before the exam.
Chances of getting more marks: When you study according to chapter weightage, you first address the chapters with the most weightage. This will thus help to get more marks than you could possibly get if you unfortunately could not cover the whole syllabus. It will allow you to test your strengths in the exam.
Increases confidence: Understanding what to study for weightage and how much importance each chapter likely has helps in eliminating confusion, and unwanted stress.

Hello,
If you have already passed Class 12 earlier and you are only taking the improvement exam in 2026, then you must choose “Passed” in the JEE Main 2026 form .
JEE Main always considers the first year in which you passed Class 12 as your official passing year. Improvement does not change that. So your status is not “appeared” and not “appearing.” It stays “Passed.”
You should enter:
-
Pass Status: Passed
-
Year of Passing: Your original Class 12 pass year
-
Marks: Your original marks (you can update later only if NTA allows it)
If you are giving Class 12 for the first time in 2026, then you must choose “Appearing.”
This is the correct and safe option for your JEE Main 2026 registration .
Hope it helps !
Hi Hriday
If your father's name is different on your Aadhar card and 10th marksheet, you need to change your father's name in the Aadhar card and match it with the spelling of the 10th marksheet, because when you take admission in college through JEE Mains score. They match your name, your father's name, and your mother's name with your 10th class marksheet, which serves as a real identity for document verification.
What college typically accepts-
- National Testing Agency(NTA), JEE Mains- NTA requires applicants to match their application name to official identity documents. These official identity documents are the PAN card, Aadhar Card, Driving License, Passport, Voter ID card and School ID card.
- Colleges Admission Authority- At the time of admission, the admission authority requires to match the application details be matched with the 10th and 12th marksheet as well as official identity documents.
I hope you will understand my point. These are some major issues which many students face during the time of admission in college.
Thank you.
Hello,
Yes, you can apply for JEE Main even if you do not have a caste certificate right now.
You only need the caste certificate if you want to claim a reserved category (SC/ST/OBC/EWS).
If you do not have it at the time of filling the form, you can apply as
General
or
General-EWS/OBC-NCL without certificate
, and later you can upload the valid certificate during counselling or document verification.
So yes, you can fill the JEE Main form without a caste certificate.
Hope it helps !
