You can't score Your Percentile on the basis of Marks because Percentile depends on a lot of other factors too which are equally important. Because Students are less this time and also Paper Variation also affects a lot. So One can't decide easily the percentile on the basis of marks.

Your Overall Percentile is: 98.33 - 98.53

Your Predicted Rank is: 13383 - 15533

So Let's Wait for the Result and Hope for the Best You will score well.

ALL THE BEST :)
