High schools often report GPA (grade point average) on a 4.0 scale. The top grade is an A, which equals 4.0. You calculate your overall GPA by averaging the scores of all your classes. This is a common scale used at most colleges, and many high schools also use it.

To convert your GPA to a 4.0 scale:

Letter Grade Percent Grade 4.0 Scale
A+ 97-100 4.0
A 93-96 4.0
A- 90-92 3.7
B+ 87-89 3.3
B 83-86 3.0
B- 80-82 2.7
C+ 77-79 2.3
C 73-76 2.0
C- 70-72 1.7
D+ 67-69 1.3
D 65-66 1.0
E/F Below 65 0.0

The chart is an example to assist in understanding the components to calculate a GPA. Your school may use a different grading scale.

Keep in mind that your high school reports your GPA to your prospective colleges. The GPA listed on your high school transcript might not be what is used by college admissions, since there is a lot of variation in high school grading scales, additional points added for honors, advanced, AP, IB courses.

For admissions, many colleges will recalculate student GPA so there is consistency/equity across applicants based on institutional standards and may not include all high school coursework or weights.

Contact your high school counselor or colleges on your list to learn more about GPA and use in the admissions process. You can also look up the academic requirements of your favorite colleges using  College Search and see how your GPA compares to students who got in and enrolled.
