how much score would be enough to get 90+ percentile....just an estimate?

Last year 100+ was 90percentile,so with that estimate, 1/3rd should be 90percentile, so for 200 marks-67, for 220-70 marks should fetch 90 percentile, but keep in mind these are estimates, it may vary on D-day with LOD

Keep an aim getting 23+ marks in each subject. i.e, 8+ questions right out of 23/24/20. That would easily fetch you 90 percentile. Good luck.

As they say 33% marks would be enough to fetch 90 percentile. Considering this year cat to be around 220 marks , 75-85 marks could be around 90 percentile i guess.

@Aditya are you presuming for out of 300 or 200? Because last year 100 marks fetched 90+ for which the paper was 300

around 130, I presume
