Are these calculators accurate?

Yes! For the University Calculator, we actively research and implement the official mathematical formulas published by the respective universities. However, we always recommend verifying your final results with your official college transcripts.

What if my university isn't listed?

If you don't see your university, send us a message via the "Contact" page with a link to your university's grading rules. We continuously add new universities based on student requests.

How does the Attendance Calculator work?

It uses basic percentage math (`Attended / Total * 100`). It then reverse-engineers the formula to tell you exactly how many upcoming consecutive classes you must attend to hit your target, or how many you can safely skip without falling below it.
