Hello

It depends on your interest. After completing B.Pharm and M.Pharm you can get a job in pharmaceutical companies as a pharmacist. If you do B.Sc. honours in chemistry or physics and after that M.Sc. you can get either go for phd or can complete B.ed to join as a school teacher or can search for jobs. So both have a lot of opportunities it depends on your interest. But B.Sc. general has less opportunities. So you can either go for B. Pharm or B.Sc honours.
Hope this helps..
