Hi aspirant,

You should have edited your details during the correction window itself but is not a major problem. You can try writing a request email to ntanationaltestingagency@gmail.com, jeemain-nta@nic.in but if in case there is no reply or help you can write the advanced exam (if qualified) as you did in jee main.

At the time of counseling you will need to carry a self attested affidavit claiming both the persons are same and it should be supported by valid documents. The verification officer will most probably approve the request and it will be sorted.

Hope it helps!!
