BEST REGARDS

Currently, there is no official release of JEE Mains 2026 registration begin. But on an average, every year there will be 11 Lakh to 12.5 Lakh students register

Hello,

If you belong to the BC (Backward Class) category, you can choose OBC-NCL in JEE Mains only if your caste is included in the Central OBC list released by the Government of India.

Here’s how it works:

  • Central OBC list: Used for national-level exams like JEE, NEET, UPSC, etc.

  • State BC list: Used only for state-level admissions or jobs.

So, if your BC caste name is in the Central list, select OBC–NCL while filling the JEE form.
If your caste is not in the Central list, choose General category, because the state BC certificate won’t be valid for JEE.

Example:
If you’re BC in Tamil Nadu but your caste isn’t in India’s Central list, you’ll be counted as General for JEE.

Hope you understand.

Hello,

No, it’s not compulsory to fill the APAAR ID in the JEE Main application form right now.

If your APAAR ID shows a “credential mismatch” error even after entering the correct number, don’t worry, you can simply leave it blank and continue filling the form.

  • The APAAR ID field is optional for most students.

  • It’s mainly for linking your academic records under the Academic Bank of Credits (ABC) system.

  • The mismatch often happens if your Aadhaar details or school record name format differ.

So, you can submit your JEE form without the APAAR ID, and it won’t affect your application.


Hope you understand.
