Perhaps unintentional spelling mistakes in the certificates alone cannot be made a criteria for rejection of a candidate. Generally the SSC certificate is taken as a base document for the purpose of name and date of birth. However the author has not made it clear in his query as to what is the status of correctness in the names in his certificates as he has mentioned only mark sheets. It depends on the extent of variation in the name also. Normally in such cases, submitting a sworn affidavit serves the purpose. My advice to the author is to take all his certificates and mark sheets to a lawyer and discuss the same in person. Depending upon the extent of variations in the name, the lawyer will be able to offer advice about requirement of the affidavit or not. However the author should not divert his attention from doing hard work for preparation of competitive examination/interview on this count.
