hello Apoorv, 

first i'd like to mention that the cut off depends on a number of factors and even category. now since

 you are from genreal, you need to score atleast 60th percentile to get a good college, that is marks 400+ would keep you in a safer zone.

again, use the college predictor link mentioned below to know better
