Have a question related to CBSE Class 12th ?
Hello,
Since you have passed 10th and 12th from Delhi and your residency is Delhi, but your domicile is UP, here’s how NEET counselling works:
1. Counselling Eligibility: For UP NEET counselling, your UP domicile makes you eligible, regardless of where your schooling was. You can participate in UP state counselling according to your NEET rank.
2. Delhi Counselling: For Delhi state quota, usually 10th/12th + residency matters. Since your school and residency are in Delhi, you might also be eligible for Delhi state quota, but it depends on specific state rules.
So, having a Delhi Aadhaar will not automatically reject you in UP counselling as long as you have a UP domicile certificate.
Hope you understand.

Hello,
Sorry, but JoSAA does not accept marks from two different boards for the same qualification during counselling. However, you can use your NIOS marks to meet the JEE Main/Advanced eligibility criteria if they are better than your CBSE marks. You can use your NIOS marks for the eligibility check, but when presenting your documents, you may be required to present both marksheets and the one with the higher marks for each subject will be considered.
I hope it will clear your query!!
