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

COMPETETIVE EXAMS in the modern world are driven by the two modes of preparation, online and offline. While offline institutes offer you excellence with their old reputed brand names, Online institutes show fast pace learning and personalized planning.

Online Coachings are better if you want to

  • Save time of travel
  • Get quality education on a cheaper price point
  • Get class recordings, to review your leanings
  • Learn at a steadier pace
  • Skip the chaotic environment one might find in an offline institute.

offline institute offer a physical teacher but as it has been seen from a general trend that students do not understand in their regular classrooms, and later learn from untrusted online sources further degrading their level of preparation.

CAREER360 provides you trust with the excellence of learning and reinforcing ideas which stand alone in this rat race of testing tirelessly for a so thought unachievable goal. You will get the rightest guidance into your exam adorned with regular testing to level up your standard.

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.

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.

Hello, Based on the current date, the application process for both sessions of the JEE Main 2025 has already been completed. The exams for 2025 were conducted earlier this year.

You are likely asking about the upcoming JEE Main 2026 examination.

Based on the schedule followed by the National Testing Agency (NTA) in previous years, here is the expected timeline for the JEE Main 2026 application forms:

For the First Session (January/February 2026):

  • The application forms are expected to be released in November or December 2025.

For the Second Session (April 2026):

  • The application window for the second session typically opens after the results of the first session are declared, which is usually in February or March 2026.

Hope it's helpful to you.

Hello,

Yes, you are right; you can upload your class 10th marksheet for the JEE Main 2026 registration, as DigiLocker documents are considered equivalent to original physical documents by law. You should download the digitally signed marksheet from your DigiLocker account to upload it to the JEE Main application form.

I hope it will clear your query!!

Hello,

As of the JEE Main January 2026 session, candidates can no longer choose their preferred exam cities. Instead, the National Testing Agency (NTA) will assign your exam center based on the address linked to your Aadhaar card.

I hope it will clear your query!!
