f your 10th and 12th mark sheets do not mention your parents' names:

1. Father's Name : Enter "Sharma Subodh" as it appears on the mark sheet, even though your full name is "Sharma Piyush Kumar Subodh."

2. Mother's Name : If not mentioned, fill in your mother's name as per official documents like the birth certificate. If there’s no official record, contact the SSC authority for guidance.

Ensure consistency between your form details and official documents to avoid issues during verification.
