Dear Gaurav,
Every company comes for on-campus placement with some set of rounds, which also demands minimum percentage criteria in your 10th and 12th. And if you do not have that much scores you won't be able to crack that company. But do not worry all company does not come out with same percentage criteria. you do your best in your post graduation. Rest make your best efforts you will get a good placement.

Since your interest area is Science you can opt for physics, chemistry and mathematics.
