Hello Amish,

I woudl like to tell you that you cannot calculate your percentile on the basis of your marks.You can calculate the percentage but percentile is different.

Below I've mentioned a formula for calculating percentile.

Percentile = (number of people behind you/total number of people) x 100

For example, if in a class of 100 students, you topped the exam. So what this means is that your score is better than 99 people and hence your percentile is 99%ile. Again, if your rank had been 30th, that means your score is better than 70 people and hence your percentile is 70%ile.

Thus in percentile, the number of people whose score is below you or the number of people your score is better than is your percentile.

Hope this helps and all the very best to you!
