To do a Btech degree you should have passed out your class 12th boards with minimum of 50% marks. After that you have to opted the entrance examination like JEE MAIN, WBJEE or your preferred institutions entrance examination. If you are qualified then basis on your rank you can go for the counsellings and choose your college. But if you have a poor marks them you can go for the management quota procedure.

Hope for the best.

Thank you.
