Hello dear aspirant.

I think you should also specify in science whether it's biology or mathematics.

For mathematics you can give exams like JEE mains exam,state level entrance exam, vitee and other private college entrance exams . NDA is also a option for you.

For biology you can give NEET EXAM. Earlier there were AIIMS and JIPMER but now they are mixed with Neet.

Moreover both stream students can also go for ssc LDC , banking etc as well as Bsc from chosen subjects.

Hope it helps you.

Good luck
