Hi Raj !

• For any standardized entrance exams such as CAT , MAT , XGMT etc , the calculation of 

        percentile is the same .

Percentage Calculation :

• Percentage is your marks divided by the total marks multiplied by 100 .

         i.e. ,

         Percentage = (Marks you have scored ) / (Total Marks Possible ) x 100 .

• For example , if you have scored 85 out of a possible 100 , your percentage would be 85 % .

• This represents a reflection of how well you have done in the exam individually. 

• It does not anything to do with how others have performed in the same exam .

Percentile Calculation:

• For calculating percentile , it is important to know the scores of other people 

        in order to calculate your own percentile . Percentiles give you an idea of how well/poorly

        you have performed in the exam . They show you how your performance is relative to that of   

        others'.

• Percentile = (Number of people who have scored lesser than you ) / (Total number of people appearing for the exam) x 100 .

• For instance , if in an exam , you have scored the second highest in the class out of 100 people .

• So this means that your score is better than that of 98 other people and your percentile would be

        98%ile.

• If your rank is 25th in the class of 100 , it means that you have scored more than the 

        scores of 75 people and your percentile would be 75%ile.

Hope this helps , all the best !
