Hey there

As you have done biology physics and chemistry in your +2 then that's very good as you have ample of options to do further.

See basically botany and zoology are vast biological branches. Botany deals entirely with the study of plants, while Zoology deals with animal studies.

So here you have to decide that during your 11 and 12 in which domain you were having more interest. Go according to that as both are best at their place.

All the best!

Thank you!
