Another observation on adding %tile marks in boards and marks of JEE main.
Since, the ranks in boards form the basis of %tile marks for boards, it will be in range of 0-100. In case JEE mains marks are distributed in smaller range (20 marks) which can happen if the test is not properly designed, the contribution of JEE main will be very small. This implies that board percentile marks will be a major deciding factor for selecting the students whose JEE advance marks will be used for making rank for IIT admissions. For other CFTIs, smaller range of marks in JEE mains and advances means that admission to specific branch will be primarily decided by board percentile score. This means normalization of JEE mains and advance marks is desirable. In order to keep the resolution high, the total marks should be as large as needed to have the earned score range almost same as %tile range i.e., 100.
