Hi, 

With your score it can't he precisely said that you have a very high chance, however there is a possibility of getting a seat under 85% state quota category.

According to last year cutoff score under 15% AIQ the cutoff for obc was around 530 however the under state counselling cutoffs tend to go down.

Keeping last years trend in mind you might have a chance. 

Having said this the above analysis is on the basis of last years data.
