Hi aspirant,

The following information furnished by the candidate CANNOT be changed after PAYMENT of registration fees:
Candidate’s name
DOB (Date of birth)
Category
OPH status
E-mail Id
Mobile number

All the other details can be edited till the last date of registration & Images (Photo, Signature and Thumb) in case if these are rejected by the AIIMS.

So you wont be able to change your email id now. Hope this helps.
