Hello,

Hello,

You may end up getting your 12th-passing state as "Haryana" instead of "Delhi" while filling out the JEE Main form, which may affect your eligibility for the Delhi state quota in JAC Delhi counseling. The state quota is based on the school board and location. Any discrepancy between the documents and application details may cause trouble during document verification.

Since this couldn't be revised during the correction window of the JEE Main, it is best to

1. Call and communicate to the NTA helpline about your particular case, so they might have some explanation for this to affect it.
2. Document verification is this stage. At JAC Delhi counseling, ensure you come forth with the right set of documents like school-leaving certificate or 12th-grade mark sheet to prove your eligibility for the Delhi state quota.
3. Counseling team alert: Report an error to the JAC Delhi authorities at the beginning stages of counseling so that they may appreciate how it might impact upon your application.

For more detailed guidance, you can check the official website of JAC Delhi or review updates and policies on sites like Careers360.
