Hello s8102003

I hope you are doing good. I would like to tell you that at 80 percentile you will not have much options in NITs. If you just want to go in NIT in any branch then only 80 percentile is sufficient but if you want to secure your future and have plans for some core branch or IT branch from NIT which have very good placement statstics then you should have atleast 90 percentile.

For your information you can calculate estimated rank by using our rank predictor
