In case your JEE score doesn't let you take admission in a good college, then don't get disheartened. Try for admission somewhere else. These days we have so many good private universities imparting quality education to the students around the world. They offer you admission on JEE scores/ tests conducted by them/ your marks in 12th. Some of these also offer good scholarships based on any one of the above mentioned admission criteria.
I think admission for most of the govt.colleges for B.Sc courses is over, there too the option available for you is some good private college/ university.
Check websites of some good private institutions that are offering quality education, ample exposure and good placements.
Good luck.
