Questions related to JEE Main

On Question asked by student community

Have a question related to JEE Main ?

Hello Swati

Yes, your EWS certificate will be valid for JEE Main 2026 and counselling if it’s issued after April 1, 2025.
This is because EWS certificates are valid for one financial year from April to March.
So, a certificate made in October 2025 will be for FY 2025–26, which covers both JEE and counselling. You’ll need the certificate number during JEE registration in October 2025.
Even if you don’t have it yet, you can still register and upload it later during counselling. Just make sure the certificate clearly mentions the correct financial year.
Always keep a few extra copies and the original ready for verification.
You're good to go if it’s issued after April 1, 2025

Hello Hitesh

  • A state EWS certificate is usually not valid for JEE Advanced or JoSAA counselling.

  • You’ll need an EWS certificate in the central government format, as required by IITs.

  • Even if issued by your local authority, it must clearly mention it’s as per Govt. of India norms.

  • You can visit your tahsildar/revenue office and request it in the “central format for JEE.”

  • Make sure the issue date is after April 1, 2025, for it to be valid in 2026 counselling.

  • You don’t need it at the time of JEE Main, only during Advanced registration and JoSAA.

  • You still have enough time to get it updated, so no stress, just don’t delay it too long.

Hello,

Yes, there are some good residential schools in Tamil Nadu that provides both board studies along with best and strong coaching for JEE/NEET.

I hope this answer helps you!

Given the condition the you were a PCB student and gave your mathematics equivalent a year later as a private candidate, you are eligible for JEE MAINS. Infact a PCB student is also eligible to take the JEE MAINS. However, the admission process into various NITS and other colleges will be slightly complex than the general admission process. Though, factually you are eligible as a candidate and as a student who is eligible for all the colleges falling under the JEE umbrella including NITS.
