I could categorise the summary.so that will make it easier. 1. Admission I am from Kerala and I joined the management quota. For that the average P.C.M score is checked.. I think it was 50 or so. The admission for me was through an educational counsellor or agent who first showed us the college. He then bargains with the college admission department and then fixes a donation cost. It is non-refundable and we pay the amount in DD. The fees were around INR 62.5k/annum.(excluding food and accommodation). didn't have to write any entrance exam or any such thing. All you need to have was the cutoff of around 50 or so if my memory is correct. The donation amount costs more for sought after courses such as Mechanical and civil etc costs more. You pay well you get the seat.
In my college the eligibility is the candidate should have 60 percentage, only then they gave admission.
