Hi, 

456 is a nice score. Go through previous year's cut off for the required college and see if your marks and ranking lies in the range on the basis of which they took admission last year. Expect a rise in that. And fee structure can only be given correctly once counselling ends. It is different for different colleges and might increase or decrease each year. 

Counselling has begun. Soon we will get the exact information for this year. Hope for the Best. 

Good Luck!
