Hello

Students are allotted subjects in class 11th on the basis of their performance in class 10th. Also, every school has its own criteria to allot the streams. You should give your best and try to score 85+ to get your desired subjects.

I would also say that if you wish to pursue MBBS only, you can take Physics, Chemistry and Biology. As according to the eligibility criteria to appear for the entrance exam (NEET), candidates must have passed 10+2 or equivalent with Physics, Chemistry, Biology/Biotechnology and English as core subjects from a recognized board.

All the Best!
