I am a student of science non medical. What are the careers options? I am personally interested in B.Tech.

If you are non medical student and your interest is in B.Tech, then don't confuse yourself. Go with your interest area. It's a good choice for a good college. You need to crack entrance exams so that you will get valuable education like IITs, NITs, etc. Birla Institute of Technology, Vellore, Christ
