FAQ
How is the percentage and letter grade worked out?
Your percentage is points earned divided by points possible, times 100. For example, 85 out of 100 is 85%. The letter grade then comes from the common US scale: 90% and up is an A, 80–89% is a B, 70–79% is a C, 60–69% is a D, and below 60% is an F. If your school uses plus and minus grades or different cut-offs, treat the letter here as the standard guide and check your own grading policy.
Is anything I type uploaded?
No — it runs in your browser. Your points are used for plain arithmetic on your device, nothing is sent to a server or stored, and the calculator works offline so your scores stay private.
Can the score go above 100%?
Yes. If you earned extra-credit points, the points earned can be larger than the points possible, which gives a percentage over 100%. The tool still shows the higher number and an A, since anything 90% or above is an A.
