It depends on many factors like how the results have come out, your AIR rank, number of candidates appearing, paper level difficulty, the state you live in, etc. At 500 marks usually in states like Maharashtra, Rajasthan, etc then at this marks you cannot get a government college and private colleges can cost you around 7-12 lakhs per annum excluding the hostel and mess fees and in some other states at this marks you can get a government seat too and government college will cost you around 1 lakh per annum.
