Greeting of the day!

Here is what Marks vs Percentile in your score range say of last year(2020).

Marks Range                      Percentile range

81 - 90                            93.4712312797351 - 94.7494792463808

91 - 100                          94.9985943180054 - 96.0648502433078

To check the full list you can go through the link below.

Now on the above analysis we can say that your percentile on 91 marks will be somewhere between 93.61 to 94.40

And on this percentile if we try to find out your expected rank then it will be somewhere between 71840 - 82000.

Having said that please note that you can observe some difference in actual percentile or rank and this score as i am doing analysis based on previous year stuffs so it can vary slightly as you know.

To check your expected rank yourself, you can go through our rank predictor too. Below I am pasting the link for it.
