Assign Grade Points: Each letter grade typically corresponds to a certain number of grade points. The exact conversion may vary depending on your institution, but it's commonly as follows:
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
F: 0.0
Calculate Grade Points for Each Course: Multiply the grade points for each course by the number of credit hours for that course. For example, if you got a B (3.0 grade points) in a 3-credit course, you earned 3.0 x 3 = 9.0 grade points for that course.
Total Grade Points: Add up all the grade points you earned across all your courses.
Total Credit Hours: Add up all the credit hours for your courses. This represents the total number of credit hours you attempted.
Calculate GPA: Divide the total grade points by the total credit hours. The result is your GPA.
GPA = Total Grade Points / Total Credit Hours
For example, let's say you took the following courses:
Course 1: A (4.0 grade points), 3 credit hours
Course 2: B (3.0 grade points), 4 credit hours
Course 3: C+ (2.3 grade points), 3 credit hours
Your total grade points would be:
(4.0 x 3) + (3.0 x 4) + (2.3 x 3) = 12.0 + 12.0 + 6.9 = 30.9
And your total credit hours would be:
3 + 4 + 3 = 10
Therefore, your GPA would be:
GPA = 30.9 / 10 = 3.09
Your GPA is 3.09 in this example.
