I have qualified HP TET and CTET after B.Ed. I want to ask that am I eligible for HP TGT, PGT and KVS TGT, PGT. I am asking this because I have done my B.Sc. in vocational biotechnology and have studied only one subject out of botany and zoology along with chemistry. Is it compulsory to study both the subjects (botany and zoology) along with chemistry in B.Sc. to apply for these test.
