Am I eligible for M.Tech after completing B.Voc (honors) in production technology?

Dear aspirant, Glad to meet you. You can not do M.Tech after B.Voc. The basic eligibility criteria for pursuing M.Tech is that, the candidate should be a B.Tech or B.E. Graduate from any recognised university. Some colleges conduct entrance exams which students need to clear to apply for M.Tech. Foo

No. You are not eligible for M.Tech but you can do M.Sc in related trade or M.Voc.

For M.Tech you need to have either B.Tech or M.Sc degree.
