Yes, you are eligible for the TGT (Trained Graduate Teacher) post for the Social Science subject with your qualifications. The minimum qualification for TGT posts typically requires a graduation degree with at least 50% marks in the relevant subject and a B.Ed. degree. You have an M.Com which fulfills the graduation requirement. While your B.Ed. is in Accounts and Commerce methods, having cleared the CTET Paper II in Social Science demonstrates your eligibility to teach the subject.

CTET acts as a national eligibility test for teachers. Clearing CTET with Social Science in Paper II specifically qualifies you to teach that subject at the TGT level.
