Which course should I pursue after completing BCA, MCA or M.Sc in IT?

M.Sc. is good to become a teaching faculty. If you want to join as a professor in private college than I suggest you to select MCA because there are so many college of MCA and they hire MCA students as BCA faculty. B.Ed. is also a good option but first check that your state government hires computer

If you are interested in teaching field then you have to just go ahead with M.Sc. as institutes need M.Sc. degree faculty. So, I will suggest you to do M.Sc. and you may also do B.Ed. It will give you strength. All the best.
