Hi, Raghunath

Considering varying trends each year it is difficult to predict the exact cutoff. However , through AIQ, the cutoff for achieving a seat is expected to be 520 around. For state quota, it will depend on various states, the number of seats , competition etc. 477 marks is a marginal marks. You have moderate chances. Wait for the seat matrix . Use careers360 rank predictor for reference 

Hello,

You have less chances for admission, according to your marks.

You can try for admission in private colleges.

Good Luck!
