Hey!
Don’t panic. If you’ve accidentally entered your father’s name instead of your mother’s in the AIIMS M. Biotech form, it won’t affect your eligibility for the exam . However, make sure to carry the correct documents (like Aadhaar, birth certificate, etc.) during counselling for verification.

You can also try to explain and request a correction during document verification or counselling stage. Many such errors are handled there.

Stay calm and focus on your exam prep.
Hope this helps!
