which college would get if my percentile is 90 and IAM obc

Hii

For your percentile your rank can be calculated as formula

(100- percentile)* number of students appeared/100

It comes in range of 86900-120000 in general category.  For this general rank your obc rank will be roughly one third of general rank.

For this rank you won't be able to get any seat in any of NITs or IIITs or GFTIs.  So  better is to focus on your April session and get better score.

Hope it helps
