Qualifying score and cutoffs are two different things. The score which you need to atleast eligible for counselling is called qualifying score. Cut off is the marks at which the last seat is given away. Cutoff is far higher than qualifying marks . Obviously not everyone who qualifies get a seat.
For general category it is 50 percentile.
For reserved categories it is 40 percentile.
Percentile is your percentage if AIR 1 marks is the total marks.
Last year it was 131 and 125 for general and reserved categories respectively.
