CBSE sent wrong formula to state boards for percentile calculation

Hot discussion that is currently going on in many high courts and Supreme court is discrepancy in normalisation calculation. HRD minister is more concern about discrepancy in top 20 percentile calculation.
When IITs published list of top 20 percentile in first week of July, it was not same as the data given by state boards. Chairman of JEE Advanced Prof H.C Gupta told that IITs have calculated the top 20 percentile of each board on the basis of the number of students who passed in that board this year, almost all school boards have calculated their top 20 percentile on the basis of the number of students who appeared for the board examination.
Because of this discrepancy admission of 79 students was cancelled in last moment when they reached respective zone for admission as they were not under top 20 percentile, though according to state boards they were satisfying 20 percentile eligibility criteria.
When state boards were asked about this calculation mistake, suddenly CBSE is coming into picture. A letter sent by CBSE chairman Vineet Joshi on June 17 to the Punjab School Education Board, a copy of which is with The Indian Express, clearly states that admission to IITs will be “based on category wise all-India rank in JEE (Advanced), subject to the condition that such candidates are in the top 20 percentile of successful candidates in Class XII examination conducted by their boards in applicable categories.” The same letter, however, gives a formula for calculating the percentile based on the total number of students who appeared for the exam and not the total number of successful candidates.
It even gives an example of such a calculation, which also shows the percentile based on the total number of candidates who appeared for the exam.
Following this formula, the Punjab board calculated the top 20 percentile candidates from the almost 3.3 lakh candidates who appeared for the exam, instead of the 2.2 lakh students who had actually passed, and prepared a list of over 67,000 students (in general category). It is learnt that over 750 students from the Punjab board have made it to the JEE (Advanced).
