Whenever a candidate does not fill out the form for a exam (i.e., a candidate have filled the form for only one or two exams out of three), or if (s)he is absent on the day of exam, then his/her result will show NA in place of any percentile.

NA = Not Applicable

For ex., If a candidate has filled the form for Paper 1 only then the result will show NA in place of any percentile for Paper 2 and Paper 3.
