hi,

see as per your interest for physics, I suggest you to go for b.sc course in physics, or you may also apply for iiser bachelors of science course in physics through kvpy exam or score in jee main or  neet exam. now for general colleges admission is generally based on 12th score, some of the university like banaras hindu university has entrance test. now coming to career option, you need to apply for recruitment exams held by state wise or centralized authority for assistant teachers position, both for colleges and schools. also to become a college lecturer you need to complete the msc course of physics. however msc courses holders has better job opportunity.after completing the msc course you may apply for engineering colleges for the position of physics faculty.

hi aspirant ,

you can choose bsc in physics after class 12th and after bsc do msc and phd in physics and give state psc exam to get recruited as government professor in college.
