Hello, I passed my class 12 with pcb but couldn't pass physic exam and because I had additional subjects physics got replaced with that and overall result was pass I gave improvement in physics but still couldn't pass . My pcb combined makes 51% . Now i don't know what to do
If you have opted for PCB at +2 level, and you are not able to clear physics exam its simply means physics is not for you. There are various subjects at UG level which doesn't required physics you can opt for that course. you should opt for same subjects at your degree level in which you are interested.
BSc biotechnology, BSc microbiology, bsc life sciences, bsc nursing or bsc in diet are still good options to consider.So First you visit any degree college and enquire about the combinations they are offering at UG level, and take a decision.
