About TallyGrade

TallyGrade is a small, independent set of free calculators for high school students, college students and parents. Every tool runs in your browser, shows its formula, and is checked against current grading and exam rules.

We are not affiliated with the College Board, any school, or any college. Results are estimates to help you plan; your school's or college's official policy always wins.

How we keep tools accurate

Each calculator page lists the date it was last checked and explains exactly how the result is computed. When an exam format or grading rule changes, we update the tool and its explanation.
