Downloading your Bihar Board 10th marksheet (2012) directly online might not be possible, as the provisional online mark sheets for that year are likely no longer available on the official website.

However,the school where you completed your 10th standard would have received and stored the original mark sheets issued by the Bihar School Examination Board (BSEB).

your best course of action is to start by contacting your former school. If that proves unsuccessful, reach out to the Bihar School Examination Board directly for assistance.

Reach out to them and inquire about collecting your original marksheet.
