Yeah, you can get admission in any engineering college by giving huge amount of money, but i don't think that's kinda a good idea. And most of the colleges are having eligibility criteria as 60% in PCM. There are many options other than engineering which you can go for, or if you are determined for engineering basically having a  B.tech degree then go to some state college,work very hard and get good grades in semesters. Or you can take drop and prepare damn well.

Hope it helps!!
