It seems that you got v low marks in entrance ....seee most of the government  colleges offers 500+ but u didn't got that much.......

But dont need to worry you will get private colleges. ...and there are many chances that you can get government college  since you are minority quotanow if u want gov't colleges than u need to take a year drop....but  Dont loose hope and dont think of dropping the year. There are some Private Universities which are very good where you can get admission on the basis of your 12th marks or entrance tests conducted by them. They provide good Infrastructure, Faculty and Placements.You should choose a college which give you opportunity to work in live projects and give you good exposure. You may browse some web sites and check their details like Lovely Professional University, KIIT University, Nirma University etc...
