MBBS is definitely not the end of road for a Bioscience student, as far as you are destined to work hard and achieve excellent career scope and prospects in whichever field you dive into.

Some of the primary career choices, I would suggest you are as follows

1. B.Sc=>M.Sc.=>PhD

2. B.Sc =>MBA

3. B.Sc => UPSC CSE /Government Services/SSC CGL/SBI PO/RRB/IBPS

4. (If You Had Mathematics in Class 12)

B.E/B.Tech => Mtech/MS/M.E.
