Understanding the Inputs
Courses
A list of all courses you want included in the GPA calculation. Each course entry requires a grade selection (A, B, C, D, F) and the number of credit hours (typically 3 for a standard semester course, 4 for lab sciences, 1 for a physical education class).
How to find it: Find your courses and grades on your report card, transcript, student portal, or class registration system. Credit hours are listed in the course catalog or on your registration confirmation.
Why it matters: Courses are the building blocks of your GPA. Each course contributes quality points (grade value times credits) that are summed and divided by total credits. Including all courses is essential for an accurate GPA.

Tips & Best Practices
- ✓ Plus/minus grades (A-, B+, etc.) often have different point values. Check your school policy.
- ✓ Some schools use a weighted GPA scale for honors and AP courses.
