Semester GPA vs Cumulative GPA
- Semester GPA: average for a single term's courses
- Cumulative GPA: overall average across all completed terms
Weighted vs Unweighted
- Unweighted: all courses carry equal weight regardless of difficulty
- Weighted: AP, honors, and college-level courses add extra points (up to 5.0 scale)
How Credit Hours Work
Each course has a credit hour value. A 3-credit class has more weight than a 1-credit class. The calculator accounts for this in its computation.

On a 4.0 scale: 3.7–4.0 is excellent (A range), 3.3–3.6 is very good (B+ range), 3.0–3.2 is good (B range). Below 2.0 risks academic probation at many schools.
Unweighted GPA uses a 4.0 max scale for all courses. Weighted GPA allows AP/honors courses to earn up to 5.0, reflecting increased difficulty.
