What is the eligibility criteria to appear in TGT or PGT exam? Can I teach mathematics in schools as I am a commerce graduate?

Dear arpit If you want to teach math subject than you should do B.ed and M.ed than you are eligible to do so. Although major of the international school require b.ed to start as teaching profession. If you would do M.ed after b.ed than you can teach to higher classes in school. All the best
