Frequently asked questions

Which calculator should I use for my class grade?
Use the grade or weighted-grade calculator when your syllabus splits the grade into categories like homework and exams. Use the GPA calculator to combine final grades across courses.
Do these match my school's grading scale?
They use the common US scale (93+ is an A, 4.0 = A). If your school sets different cutoffs, the percentage is still exact — only the letter mapping may shift.
Is anything saved or sent anywhere?
No. Every calculation runs entirely in your browser. Nothing you type is uploaded, stored, or shared, and no signup is required.
