Questions about Grade Calculator

Can I change the letter-grade scale?

The current interface shows a common reference scale. Use your official syllabus to interpret the percentage when its bands differ.

What if my teacher uses a different letter scale?

Use the percentage result, then compare it with the bands in your syllabus. The displayed A–F band is only a common reference.

Can earned points be higher than possible points?

Yes, if genuine extra credit allows it. The resulting percentage may be above 100.
