Simran,  Was your board copy checked?

Please simran tell me your exam will be rejected or not because i also do this mistake

Hey Simran, Set no. and code no. are meant for proper distribution of answer sheets. Since you have not written these things your sheet might get misplaced but there are fewer chances of something like this to happen.

If you have written other details like Centre Code, Roll no., School code, etc. then your answer sheet will not be rejected and there will be no problem in checking.

Hope you will understand.

For any other query regarding this please ask in comments.
