QnA related to JEE Main

Ask your question related to JEE Main

Hello,

If your family income is actually less than Rs. 1 lakh, then you must correct it during the JEE correction window .
If you keep the wrong income (up to Rs. 1 lakh), the college may not give you fee waiver or EWS-based tuition fee benefits. So correcting it is better.

About the correction fee:
Usually, JEE does not charge extra for changing basic details like income or category documents during the correction window. But if you change something that affects the application fee (like category), then a fee difference may apply.
For income detail change only, you normally do not need to pay anything .

So yes, correct it if your real income is below Rs. 1 lakh. It will help you during counselling and fee waiver.

Hope it helps !

Hello,

It should not cause a big problem , but you must correct it during JEE Main form correction window .

Here is the simple rule:

  • Your JEE application name must match your Aadhaar details as much as possible.

  • If you wrote only name + surname from your Class 10 marksheet, and your Aadhaar has name + father’s name + surname , then it is better to update it in the correction window .

What to do:

  1. Wait for the form correction window to open.

  2. Edit your name in the JEE form to match your Aadhaar card .

  3. Save and submit.

If correction is allowed, everything will be fine.

If correction is not allowed, don’t worry too much. Carry your Class 10 certificate and Aadhaar card during exam, the NTA usually accepts it if your identity is clear.

Hope it helps !

Hello,

No, there is no correction window for changing your Aadhar photo after you have already submitted the JEE form, and it could be a big issue during the exam. You must visit an Aadhaar enrollment center to update your Aadhaar photo, which can't be done online.

I hope it will clear your query!!

Hey there,

Your OBC-NCL certificate will not be valid for the JEE Mains 2026 application as it is from June 2024. You can apply for a new one as soon as possible. For the JEE Mains, the OBC-NCL certificate should be issued on or after 1 April 2025.

And as for your Aadhar, the mistakes in your name and Date of Birth will be an issue during the document verification process. The details should match your 10th-class certificate. So you will also need to update it as soon as possible.

Hope it helps!!!

The difficulty of the JEE Main exam is consistently rated as moderate to tough, making it one of the most challenging entrance tests globally.

Here's a breakdown of why it's considered tough and how the difficulty is managed:

Difficulty Factors

  • Vast Syllabus: It comprehensively covers the entire Class 11 and 12 Physics, Chemistry, and Mathematics (PCM) syllabus. You must master all concepts from the NCERT curriculum and beyond.

  • Speed vs. Accuracy: The exam requires you to solve many complex problems in a limited time (typically 90 questions in 3 hours). The challenge isn't just knowing the answer, but applying concepts rapidly.

  • Conceptual Depth: Questions often test deep conceptual understanding and application rather than simple memorization of formulas.

  • Subject Variation: While Physics and Chemistry often remain manageable, the Mathematics section is frequently cited as the most lengthy and difficult part of the paper.

Strategic Approach

The key to succeeding in a tough exam is not worrying about the overall difficulty, but developing a strategy based on analysis.

  • Analyze Trends: By studying previous year papers, you can pinpoint specific topics that carry the highest weightage and practice them extensively.

  • Regular Mock Tests: Consistent practice under timed conditions helps you simulate the exam environment and improve your decision-making and time management skills.

Hello Satyam,

Yes, your EWS certificate is valid.

In Bihar, the EWS certificate can be issued by the Circle Officer, BDO, SDO, or DM. So a certificate signed by the Circle Officer (Revenue Officer) is acceptable.

If the format of your certificate is the same as the Central Government EWS format, then it is valid for JEE Main registration and also for JoSAA counselling. The heading “Government of Bihar” does not create any problem.

Just remember one point:
For JoSAA 2026 , you will need an EWS certificate issued on or after 1 April 2025. Even if your current certificate works for registration, you must update it before counselling.

Hope it helps !

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 -

  • Children of professionals like doctors, lawyers, and engineers, as well as government officials in Group A and Group B services, are generally considered in the "Creamy layer" category.
  • Your current unemployment does not change your occupational status. The eligibility is based on your profession, not your current job status.

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
