Hi
Try ur luck in the 4th counselling, there might be some vacancy where u can get a seat. Else, go for the state counselling. Get info on the best of ur state colleges that take admission on the basis of ur state rank AIEEE. 
Else there are some private colleges too  which take admission bt do make u pay a lot . So, my advice would be to prepare fr the entrance xams fr 1 more year rather than going into any unrecognised college. If u are not sure that whether u wud be able to cope up with it, then that's something u urself have to decide.
Would u mind just studying hard for one more year and make something good of ur future. U need to be confident about urself that u will study hard and u need to commit to ur decision, coz dropping an year and wasting it wud lead u to nowhr and also a wasted year.
So, think about ur goals and then make a decision , what u really want to do in ur future. Getting into any college wont do any good, so think about it.
Best of Luck!!
