Frequently asked questions
Is my data private?
Yes. Everything is calculated in your browser — your grades never leave your device.
How is GPA weighted?
Each grade is converted to points (A = 4.0, B = 3.0, …), multiplied by the course credits, summed, and divided by the total credits — so higher-credit courses count more.
Which grade scale does it use?
A standard US 4.0 scale with pluses and minuses (A+/A = 4.0, A− = 3.7, B+ = 3.3, and so on down to F = 0.0).
Can I use it for a semester or cumulative GPA?
Both — enter one semester's courses for a semester GPA, or all your courses for a cumulative GPA.
