Every letter grade a student receives is worth a specified number of grade points depending on the number of credits the class was taken for. The GPA is the sum of the grade points earned divided by the total number of credits taken. To come up with the number of points, you must first convert the letter grade into numbers. The following chart displays the conversion of letter grades into numbers that can be used to figure out GPA.
Letter Grade/Number Equivalent
Example of GPA Calculation
Spring 2011 Grades for Sparky
- BIO 181, 4cr, Grade Earned: A
- PGS 101, 3cr, Grade Earned: C+
- MAT 265, 3cr, Grade Earned: B
First convert the letter grade into the number equivalent. A- = 3.67, C+ = 2.33, and B = 3.0.
Next multiply the number of credits by the letter grades number equivalent. So for BIO 181, you would take 3.67 x 4 = 14.68 grade points. For PGS 101, 2.33 x 3 = 6.99, and MAT 265 3.0 x 3 = 9 for a total of 30.67 grade points.
Now add up the number of grade points and divide that by the total number of credits (in the above example 10 credits is the total number). So, 30.67 / 10 = 3.067, the cumulative GPA for this student (assuming this is his/her first term at ASU).
Semester vs. Cumulative GPA
Semester GPA: GPA consisting of credits earned in a specific semester. The method described above can be used to calculate your semester GPA.
Cumulative GPA: GPA consisting all the classes you have taken at ASU. You can find the cumulative GPA on your unofficial transcript through MyASU. Please work with your advisor if you want to find your cumulative Transfer + ASU GPA.
