Hello student ,

As you have not mentioned for what you have forget your registration number . That's why it would be tough to solve your query but still you don't need to worry either ask your question again with some details like for what you have forget your registration number or you can simply visit the official website and enter your hall ticket number and date of birth, from there you will get your registration number. Else you can send mail for your issue to that particular website .

Hope it helps !
