### ISC 2016 Estimated Percentage to Percentile Conversion

Approximate Percentage to Percentile Conversion for 2016 Examinations of Class 12
Formula Used:

Percentile of Student X = 100 - 100* (Number of students ahead of Student X)/(number of students in the combination pool)
This is a slightly simplified approximation of the actual formula, which also takes into account half the number of students getting exactly the same score as X.
Since we pulled out all the ISC-2016 data, we thought, you may be interested in Percentage to Percentile conversions. Here they are.
Estimated/Approximate Percentage to Percentile Conversion for the pool of ALL STUDENTS (regardless of subject combination)
