The performance of a student in a given course is made through continuous and summative assessments. That comprises quizzes / in-course, class participation, attendance, homework/assignment, case study, class test, mid-term and semester final examinations. Letter grades and grade points are used to evaluate the performance of a student in a given course. A+, A, A-, B+, B, B-, C+, C ,and D are the passing grades while F is the failing grade. Letter grades and corresponding numerical grades used in calculating the GPA/CGPA (Cumulative grade point average) are as follows:
| Marks Range | Letter Grade | Grade Point | |
| 80% and above | A+ | A Plus | 4.00 |
| 75% to less than 80% | A | A Regular | 3.75 |
| 70% to less than 75% | A- | A Minus | 3.50 |
| 65% to less than 70% | B+ | B Plus | 3.25 |
| 60% to less than 65% | B | B Regular | 3.00 |
| 55% to less than 60% | B- | B Minus | 2.75 |
| 50% to less than 55% | C+ | C Plus | 2.50 |
| 45% to less than 50% | C | C Regular | 2.25 |
| 40% to less than 45% | D | D | 2.00 |
| Less than 40% | F | 0.00 | |
Grade Point Average (GPA) is the weighted average of the grade points obtained in all the courses attempted by a student. The four-step procedure that will be followed to calculate the CGPA (Cumulative Grade Point Average) of a student is given below:
For example, if a student attempted n courses in a semester having credits C1, C2, ..., Cn and his/her grade points in these courses are G1, G2, ..., Gn respectively, then the CGPA can be calculated as follows:
CGPA = (Σ (Credit of the course attempted × Grade point earned)) ÷ (Σ Credit of attempted course)
CGPA = (Σ Ci × Gi) ÷ (Σ Ci)
A Numerical Example
Suppose a student has completed six courses in a semester and obtained the following grades:
| Course | Credit (Ci) | Letter Grade | Grade Point (Gi) | Ci × Gi |
|---|---|---|---|---|
| MAT 111 | 3.0 | A+ | 4.00 | 12.00 |
| ECO 101 | 3.0 | A | 3.75 | 11.25 |
| CSE 101 | 3.0 | A+ | 4.00 | 12.00 |
| STA 101 | 3.0 | F | 0.00 | 0.00 |
| ENG 101 | 3.0 | A | 3.75 | 11.25 |
| MAT 121 | 1.5 | B | 3.00 | 4.50 |
| Total | ∑Ci = 16.5 | ∑Ci × Gi = 51.00 |
CGPA = (Total Grade Points Earned) ÷ (Total Credits Attempted)
CGPA = 51.00 ÷ 16.5 = 3.09
Note: If the 3rd digit after the decimal point is above '0', the grade will be rounded (ceiling) into the second digit after the decimal. For example, 2.990 will be counted as 2.99 while 2.991 will be counted as 3.00 in CGPA calculation.
