HELLO,

Class 10th and 12th mark sheets are the most important document and you can not have any mistake on them. But by chance if you have, CBSE provides a chance to correct it. You need to follow the following steps:

1. Download the application form from https://www.cbse.gov.in/ and take its print.
2. Fill the application form and you cannot tolerate to have mistakes this time so please check before submitting it.
3. You need to submit your leaving certificate provided by schools and portion of the page of admission and withdrawal register of the school where the entry has been made with respect to the candidate.
4. Pay the correction fees (for your name it is Rs. 1000 and Rs. 1000 and cost of document for Mother's/Father's name).

After you have completed all these steps, board will make corrections in a time period.

Hope it helps.
