Hi,

In B.Sc non medical branch, physics and chemistry are complusory subjects the rest can be changed but these two cannot. 

Good luck!

Hey!

It is not possible to omit chemistry and take any other subject in non-medical stream. Chemistry is one of the core subjects in science. Even if you try to pursue B.Tech. or any other science courses, chemistry will be a part of curriculum later during your degree courses for sure (not whole Chemistry, but many topics).
Also, chemistry and physics have many overlapping concepts: concepts which are common in both physics and chemistry.
So, instead of thinking of chemistry as a burden, you should invest more time in studying and clearing concepts of the subject. The key is to know the reasons behind the phenomenon/reactions etc. and grasp the concepts.


Best wishes!
