Which course should I pursue after completing B.Sc in BZC, M.Sc, B.Ed or Diploma?

Well, it depends on what you want to do with your study. I mean, if you want to enter the teaching field, then B.Ed or M.Sc would be a better choice or to enter the technical field Diploma would be a good choice.

If you are targeting to be a primary school teacher, then go for B.Ed, but if you are seeing your career as to be a professor, you must go for M.Sc.

If you are targeting teachers job as TGT or primary school teacher, you may opt for BEd now.If you are targeting PGT job then you may do M.Sc B.Ed. If you want to be a professor in college or university then you may opt for M.Sc PhD and NET.
