Hello Vivek

As you know the cutoff's are yet not released so it is difficult to predict the colleges. But you can use the rank formula You can calculate the predicted rank using the below formula but you cannot calculate the score using the percentile.

((100-percentile)*875000)/100

Your approximate rank will be around 75k( Not the Category rank). With this rank you can realte your category rank and match it with last year's cutoff.

Hello Vivek

Well, it's very difficult as of now,to predict the cutoff for colleges of JEE mains and for jee advance based on percentile.You can first calculate your rank by rank=(100-percentile)*874469/100.With this rank,you can compare previous year's cutoff for different colleges and can predict some of the colleges you may be getting and also the advance cut off.But remember this is not the final rank.It will change based on the april session of mains.To further predict colleges visit https://engineering.careers360.com/jee-main-college-predictor  .Hope this helps.

Good Luck
