Hi,
The Duration of B.Sc (Microbiology/ Botany/ Chemistry) is three year duration in any Indian university as per UGC Guidelines. You should have HSC as an eligibility for that.

I think, in most of the colleges, the eligibility is 60% marks in class 12th. But, you can check on the colleges site for which you want to apply.

Hi,
You can pursue any as per your area of interest. What actually matters for IAS Entrance is your knowledge and command on the subjects.

Check out all possible graduation option and then take final call as per your interest area. All the best.
