- The number of credit hours earned for each course
- The letter grade received for each course
- The numerical grade point value associated with each letter grade
Here's the basic formula to calculate GPA:
```
GPA = (Total grade points earned) / (Total number of credit hours attempted)
```
To determine the total grade points earned, multiply the grade point value for each course by the number of credit hours for that course and then sum up the results. For example:
- Course 1: 3 credit hours, B+ grade (3.5 grade point value), so grade points earned = 3 * 3.5 = 10.5
- Course 2: 4 credit hours, A- grade (3.7 grade point value), so grade points earned = 4 * 3.7 = 14.8
- Course 3: 2 credit hours, C+ grade (2.5 grade point value), so grade points earned = 2 * 2.5 = 5
Total grade points earned = 10.5 + 14.8 + 5 = 30.3
To determine the total number of credit hours attempted, simply add up the credit hours for all courses. In this example, the total number of credit hours attempted is 3 + 4 + 2 = 9.
Finally, divide the total grade points earned by the total number of credit hours attempted to calculate the GPA:
```
GPA = 30.3 / 9 = 3.37
```
Therefore, the GPA for this student is 3.37.
