Welcome prabhnoor!

If you want to know your roll number for class 10th examination then you must check your admit card because admit card has all the relevant details like the roll number, the centre address, the date of examination, etc.

If you have not get you your admit card till now then you must visit your school and ask for admit card in the school office they will provide you admit card and then you may check it.

Thankyou:)
