The academic year is divided into trimesters. Students are graded at the end of each trimester. The lowest possible passing grade is a D- or a numerical score of 60. Letter grades have these numerical equivalents:
| A+ = 97-100 | B+ = 87-89 | C+ = 77-79 | D+ = 67-69 |
| A = 93-96 | B = 83-86 | C = 73-76 | D = 63-66 |
| A- = 90-92 | B- = 80-82 | C- = 70-72 | D- = 60-62 |
| F = 0-59 |
