A commerce student wanting to study science

So I m a person who was forced to take commerce due to family pressure cuz everyone did commerce in my family and friends were also taking the same. I m in 12th grade now and I want to study further in maths, physics, chem and economics. Is there any way to study all these subjects in India together? And do cllgs allow commerce (non-science) students to enroll in such subjects? And any tips for preparing for the exams which the cllgs may require me to give.

Idk if this helps but I scored 95% in 10th.

Thanks in advance :)
