Hi Ritu,

Yes there exists M.Sc. in chemistry, which is a 2 year post graduation course. It is usually done by people who complete their graduation in the same field. There are many job opportunities available after completing post graduation.

Now as you are pursuing B.Sc. medical, you need to be assured that there is no need to fear from Mathematics anymore as there is no such subject in your course. Your core subjects will just include - Chemistry, Zoology, Botany, Computer science and General english.

Hope this helps.

Good luck.
