Dear Harsh,

Don.t worry as the 12 marksheet is required at the time of counselling or during  the time of orientation programme.

If you have not got your marksheet then there won't be any issue with that as the certificates and marksheets are checked on the day of counselling and by that time if you don't get it you can just tell the invigilator on duty that you have not received your marksheet yet. The purpose of the counselling session is to check that whether the candidate details mentioned in the form are authentic or not, are you legalized to take admission in their college (basically a small screening process) and all this will be done with 10th marksheet and other certificates.

Mostly, the marksheet verification is conducted at the time of orientation programme when you have actually taken admission in that particular college and by that time you would have received your marksheet.

Also, keep confirming about the marksheet arrival in your school as the school will be providing the marksheet once they get it from the board.
