Please score as much as you can. 

The cutoff can be be really unpredictable. 

For eg:530 marks were enough to get admission in 2015 in Delhi for Delhi quota general students but in 2017 580 marks were required. 

Everything depends on the level of exam.

Best of luck. 

The cut off varies college to college but with 550 marks chances of getting college under AIQ would be tough as it requires 580+ but with these marks state colleges (85% quota) you can get but it also depends which state you belong to so it would be good if you could tell which particular state domicile you are having accordingly I would be helping you with the required score.

Good Luck!!!
