Hi Ranjeeta,

I think you forgot to mention the name of exam you are referring to.

Whenever you forgotten your username or password of any of exam or any college then you are required to mail the authorities explaining your issue and request them to find your username & password and let yourself know about the same.

If you would have mentioned the name of exam, I would have helped you in a better way.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!
