Hi Ayush!

I am considering that you asking for chooseimg subjects in context of 11th and 12th class. And as you have mentioned about biology, so physics , english and chemistry are the mandatory subjects. if you take biology as the main subject then you will be counted as a medical students (PCB student, if you do not have mathematics). And medical stream is definitely a demanding stream until unless you are interested in becoming a doctor or enter into medical career. And the additional subject you have chosen in comouter science which is no doubt a sage choice as the upcoming years are directing us to move into the digital era. So, overall the subjects choosen by you are beneficial.

Thankyou!
