According the new policy the formula for calculating percentile is given below for the students of BISE:
Formula for Calculating Percentile Relative Grading System
Percentile Score = Marks Obtained by Candidate * 100
Maximum Marks Obtained in Subject
The letter Grades & Corresponding Percentile Scores are as under:
| S.No | Boundaries of Score | Letter Grades |
| 1 | 90-100 | A+ |
| 2 | 87-89 | A |
| 3 | 82-86 | B+ |
| 4 | 77-81 | B |
| 5 | 70-76 | C+ |
| 6 | 60-69 | C |
| 7 | 50-59 | D+ |
| 8 | 40-49 | D |
| 9 | 33-39 | E |
| 10 | 32 & Below | Less than 33% |
