Yes, degree or equivalent Diploma in education is mandatory for TGT and PGT government teacher.

It depends on the country, degree you want to lecture and the University. But, these days you should have a Ph.D Degree, teaching experience and some published research.

SET exam is entrance exam for pursuing BBA and BBA (IT). For becoming a teacher in Higher Secondary school, M.Com is enough for you.

Sorry, you need to choose the same or related subjects in NET exam in which you have done your PG.

To become lecturer, you have to do LLM, and then do Ph.D for government school/college.

No, part time courses doesn't consider complete degree. They might be your experience.

You should try to clear CTET and your state government teacher eligibility test.
