can i take physics chemistry without taking botany while doing zoology honors
See which subject combination you may or may not take is entirely dependent on the college you are in. So you can take admission to the course of Zoology with Physics and Chemistry as Generic Electives. But in general, the combination for the Zoology is Botany and Chemistry. Now if your college allows it then you can definitely go for it or you can find out a college which offers this combination and then apply for the course.
