Terms of Use

Last updated June 5, 2026

By using this site you agree to these simple terms.

Informational use only

The calculators and guides on this site are provided for general informational and educational purposes. Results are estimates. These are grade estimates, not official academic figures — your school’s published grading policy and your instructor are the authority on your actual grade.

No warranty

We work hard to keep the formulas correct and show them openly, but the site is provided “as is,” without warranty of any kind. We are not liable for decisions made based on a result — always verify anything important before acting on it.

Affiliate links

Some outbound links may be affiliate links; see our Privacy page for details. Prices and product availability are set by the retailer, not by us.
