Dear Aspirant,

This is almost impossible to predict how many marks will get you any percentile as the percentile is the relative criteria and depends upon many factors like the difficulty of the exam, number of test takers, etc.

So If you are aiming for 90 percentile it is not easy to predict the marks, but since the previous data is there, we can say that you need about the 35-40 out of 100 marks in each subject to get the 90 percentile.

Hope this helps. Thank you.
