Take this chance to check your other documents (PAN card, Aadhaar, Voter’s ID etc).
Check whether you have any ID document that has your full name correctly without any spelling mistake. If you have a valid birth certificate, PAN Card or Voter’s ID that has your correct name, then you can approach the board via the head of the institution to issue you a new marks card.
If not or they do not accept, then approach a Notary in your area who can get you a valid affidavit that has your proper name. Once this is done, please visit the newspaper offices to place a name correction/change advertisement in one English and one vernacular paper and keep the original paper snippets with you.
Then draft a letter to the respective 10th and 12th boards requesting the name correction service you need, forward it via the respective principal/head of the institution. You would need to pay a small fee for this service.
In 3-4 weeks the board will despatch your certificate to the respective school/college.
Please keep the acknowledgment number and payment reference number handy in case you need to contact the boards during delays in the process.
If you have done you CBSE, then the process is the same and there is a regular form to be filled, signed by the principal and submitted to the CBSE board.
