To calculate your GPA (Grade Point Average), follow these steps:
1. Determine the Point Value of Each Letter Grade
First, you need to know the point value assigned to each letter grade in your grading system. A common system is:
Letter Grade | Point Value |
---|---|
A | 4.0 |
A- | 3.7 |
B+ | 3.3 |
B | 3.0 |
B- | 2.7 |
C+ | 2.3 |
C | 2.0 |
C- | 1.7 |
D+ | 1.3 |
D | 1.0 |
D- | 0.7 |
F | 0.0 |
Note: This table represents a common grading system. Your institution may use a different system, so check with them for the correct values.
2. Calculate Quality Points for Each Course
Multiply the point value of the letter grade you received in each course by the number of credit hours (or units) the course was worth. This gives you the quality points for that course.
Example:
- You earned a "B" (3.0) in a 3-credit course.
- Quality points for that course: 3.0 * 3 = 9.0
3. Total the Quality Points
Add up the quality points you earned for all courses.
Example:
- Course 1: 9.0 quality points
- Course 2: 12.0 quality points
- Course 3: 6.0 quality points
- Total quality points: 9.0 + 12.0 + 6.0 = 27.0
4. Total the Credit Hours
Add up the total number of credit hours for all courses you took.
Example:
- Course 1: 3 credits
- Course 2: 4 credits
- Course 3: 2 credits
- Total credit hours: 3 + 4 + 2 = 9 credits
5. Calculate the GPA
Divide the total quality points by the total credit hours.
Example:
- Total quality points: 27.0
- Total credit hours: 9
- GPA: 27.0 / 9 = 3.0
Therefore, your GPA is 3.0.
In summary, the formula for calculating GPA is:
GPA = (Total Quality Points) / (Total Credit Hours)
