Science

Hi Shivangi,
You can shift from Science to arts definitely after class 12th.
But, one thing to make sure if you want to go for arts with maths, then you need to have had maths in your class 11th and class 12th Science grades. If you do have maths there, then I don't think there'll be any issue for enrolling for the same. But up to my knowledge you won't be able to pursue B.Sc Maths with an arts pass out after class 12th, as the requirement for B.Sc is some aggregate percentage in class 12th Science. Hope it helps.

You can pursue a B.Sc (General) - Three Duration Degree, which will add Statistics, Economics & Political Science as Subjects in it. But, it will be equivalent to a Degree in Humanities Stream. So, you can pursue an MA (Economics), MA (Political Science) and an M.Sc (Statistics).

Being a B.Sc (Hons) (Zoology), you can pursue a M.Sc (Zoology), M.Sc (Bio-Technology), M.Sc (BioInfomatics), M.Sc (Forensic Science), MBA , etc.

Your percentage should be above 85 to take the entrance exam of B.Sc Hons. There is no subject marks considered only your percentage will be considered. Good luck.
