Take the grades here as a quick guide, not an official mark. Here is where they stop.

Your school\'s scale wins

The letter grades use the common US scale, but many schools differ: some start the A at 93, some add pluses and minuses, and some weight assignments in ways a simple percentage does not capture. Your official grade is the one your school records, not this calculator.

Weighting is simplified

The final grade page assumes the final is a single weighted slice and the rest of your grade is fixed. Real courses mix homework, quizzes and participation with their own weights, so treat the figure as a target, not a guarantee.

Not academic advice

This is a calculator, not a guidance counsellor. For anything that affects your standing, credits or eligibility, check with your teacher or school.

The bottom line

We use standard formulas and take care, but we can't promise a result matches your course rules, and we take no responsibility for decisions made on the strength of it.
