Dear Himanshu,

If you score 99 percentile in JEE Main then your general rank or say All India Rank will be somewhere between 10230 - 11500.

You can also check your expected rank by yourself using our rank predictor tool. Below I am attaching the link of it.

You should note that these ranks are calculated on the basis of past years Percentile vs Rank trends, so you should not be surprised by observing slight variation in the actual rank and the expected rank.

Now if we do some more analysis then your category rank which is OBC will be somewhere between 2200 to 4000 according to some previous year Percentile vs Rank analysis for OBC.

Now coming to your third question which how much you have to score to get 99 percentile.

So for this you have make sure that you score 155+ out 300 total marks in JEE Main to get 99 percentile or more.

I hope this information helps you.
