Hello,

If you want Science stream for graduation but not much hard then choose zoology honours. It's generally easy than another Science subjects.

But for this course you have to biology in your class 12th. Because mathematics, chemistry and physics are generally good subjects but tough subjects for honours. Also you can do BSC in microbiology it's also an interesting subject or BSC in biotechnology. But zoology is easiest subject . So choice is yours. And you are going for banking department then you have to extra studies for backing job examination.

All the best.
