Reporting a wrong answer
This is the message we most want to receive. A grade calculator that is quietly wrong is worse than no calculator at all — someone walks into a final believing they need 62% when they need 81% — so a correction gets looked at before anything else.
The most useful report contains five things: the page address, exactly what you entered, the answer the page gave, the answer you expected, and where your expected answer came from. That last one matters more here than on most sites. Most disagreements about a grade turn out to be a difference in rules rather than a bug in the arithmetic: whether your school drops the lowest score, whether an A+ is worth 4.0 or 4.3, whether the final replaces a test rather than being added to it, whether extra credit is inside the category weights or on top of them, whether 89.5 rounds up. If you can say which rule your school uses, that usually settles it in a sentence. Either way we will tell you what we found.
If the disagreement is with your teacher's own gradebook, their number is the one that counts. We would still like to hear about it, because a rule we do not model is a page we could improve.
How to reach us
One address, for everything: hello@thegradecalc.com.
It reaches a person rather than a ticket queue. There is no contact form here, deliberately — a form would mean collecting your details on our side, and the privacy policy only stays as short as it is because we do not. Corrections are read first; everything else gets a reply when there is something useful to say, which is not always the same day.
Other reasons to write
- A calculator we are missing. Especially if you can say what you were trying to work out and which site you ended up using instead.
- A grading scale we do not cover. We use the common US letter bands and the 4.0, 4.3 and 5.0 point scales, listed in full on the letter grade to GPA page. Schools that use a 100-point GPA, a 12-point scale, or their own honours weighting are not covered, and we would like to know which ones you have run into.
- A course-difficulty bump that is wrong. We apply +0.5 for honours and dual enrolment and +1.0 for AP and IB, because those are the most common. Plenty of districts do something else.
- A page that is hard to read or hard to use. Including with a screen reader or a keyboard. These pages are meant to work without a mouse and without JavaScript; if one does not, that is a bug.
What we cannot help with
We cannot tell you what your grade is. We do arithmetic on the numbers you type in; your instructor and your registrar decide what your grade actually is, and their rules beat ours every time. See the terms of use.
We also do not answer homework questions, do not write or check essays, do not offer any opinion on where you will be admitted or what GPA you need for a particular school, and cannot change, appeal or look up a grade on your behalf. There is nobody here with access to any school's records — this site is a set of static pages and a few hundred lines of arithmetic.
What not to write about
We do not accept guest posts, link exchanges, sponsored content, paid placements or “broken link” outreach, and we do not add outbound links in return for anything. The answer is no; please do not follow up.
Privacy questions
Nothing you type into a calculator on this site reaches us, so there is no record of you here to ask about — the privacy policy explains why in detail. Questions about that policy, or about advertising cookies set by our advertising partner, go to the same address: hello@thegradecalc.com.
