Questions

High school GPA calculator FAQ

Can I calculate weighted GPA with these tools?
RapidTables supports weighted GPA by entering credit hours and using a weighted average formula. Omni Calculator provides both unweighted and weighted scores but does not require credit inputs.
How many courses can I enter?
Omni Calculator allows up to 20 courses. RapidTables does not specify a limit but its interface suggests a smaller, credit-focused entry grid.
Do I need to know my credit hours?
RapidTables requires credit hours for each course to calculate a weighted GPA. Omni Calculator works with just letter grades if you only need an unweighted result.
Which tool gives a cumulative GPA?
Both tools calculate cumulative GPA, but RapidTables includes an optional field for previous cumulative GPA and credits, making it better for tracking across semesters.
Are the grading scales the same?
Both use standard A+ through F scales, but RapidTables maps A+ to 4.33 and A to 4.00, while Omni Calculator’s scale matches typical school reports.
