How to use the GPA calculator
This workspace combines semester blocks, per-course letter grades, credits, and an optional weighted policy so you can see both term and cumulative GPA on one screen.
- Each semester lists courses with grade, credits, and weight (for high-school style weighting).
- Turn Weighted on when you want honors/AP-style bumps applied to that term.
- Add semesters or courses as needed; totals refresh automatically.
Step-by-step tutorial
- Start with Semester 1: enter a course name (optional), pick a letter grade, and set credits (often 1.0 per class in high school).
- Choose a course weight if your school distinguishes regular, honors, or AP-style rigor.
- Use + Add Course for more rows, or add another semester when a new term begins.
- Watch the semester GPA line and the cumulative gauge update as you edit inputs.
- For college credit-hour math, open the dedicated College GPA calculator.
Tips and tricks
- Align credits and weight rules with your transcript or handbook before sharing numbers with advisors.
- Snapshot your term mid-semester to see how one grade change moves the average.
