Hello Suhana

If you want to prepare for the JEE Mains exam 2026, then you need to manage your study time and try to give very much attention to your studies. JEE Mains is an entrance exam which is conducted by NTA(National Test Agency), and only science stream students give this exam to get admission in top engineering colleges to get admission in B.Tech or B.E courses.

Students give this exam after completing or appearing in the 12th class. This entrance exam is conducted at the undergraduate level. After clearing the JEE Mains exam, you become eligible to give the JEE Advanced, which helps to get admission in top IIT & NIT colleges of our country.

Here are some tips which help you at the time of your preparation-

  1. Cover the whole syllabus of JEE Mains
  2. Try to manage the study time
  3. Use the NCERT book for better preparation
  4. Give more mock papers and solve the previous question paper
  5. Manage the time & give some time for revision

I hope this information he;lps you. You also do your preparation on our official website, careers360.

All the best for your exam.


Hello,

Yes, you are eligible to attempt JEE Main 2026, as eligibility is based on appearing for or passing the class 12 exam in 2024, 2025, or 2026. Since you passed Class 12 in 2024, you are within the eligibility window to appear in 2026. Here in this article you will find more about the JEE Main eligibility criteria.

I hope it will clear your query!!

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 !
