Plain-language terms for using this site. Last updated .
This is not an official record of your grades
This is the important one. The calculators here do arithmetic on numbers you type in. They do not know your school, your syllabus or your instructor's rules, and those rules genuinely differ from one classroom to the next.
Every one of the following changes the answer, and none of them is visible to us:
- whether the lowest score in a category is dropped
- whether the final exam replaces a test rather than being added alongside it
- how the school rounds — whether 89.5% is an A− or a B+, and whether rounding happens once at the end or at every step
- whether extra credit sits inside a category's weight or on top of the total
- whether plus and minus grades are used at all, and what point values they carry
- which GPA scale applies, whether an A+ earns 4.0 or 4.3, and how an honours, AP, IB or dual-enrolment course is weighted
- how transfer credits, pass/fail courses, withdrawals and incompletes count toward a cumulative GPA
Where this site and your school disagree, your school is right. The number on your transcript is set by your instructor and your registrar. Treat anything computed here as an estimate to check against them, not as a result — particularly before dropping a course, before deciding how much to study for a final, or before reporting a GPA on an application.
Not admissions, academic or career advice
Several pages mention what a given GPA or class rank tends to mean. Those mentions explain why people look the number up. They are not a prediction, not an evaluation of your chances anywhere, and not a recommendation about what to take, what to drop or what to apply for. Nobody here has seen your record. Talk to your school counsellor or your academic adviser, who has.
No warranty
The site is provided as it is. We take correctness seriously — every formula is checked on every build against an independent implementation of the same arithmetic, the grading tables the pages display are asserted to match the tables the calculators use, and known-good values are held in the test suite — but we do not warrant that every answer is correct for every purpose, and we accept no liability for a decision made on the basis of one. If you find an error, please report it; that is the fastest way to get it fixed for everyone.
Acceptable use
Use the calculators as much as you like, for anything, including grading a class. There is no account, no quota and no licence to buy. Do not scrape the site at a rate that degrades it for other people, do not attempt to interfere with it, and do not republish the generated pages wholesale. Linking to any page is welcome and needs no permission — including a link with your numbers already filled in, since every calculator writes its inputs into the address bar for exactly that reason.
Advertising
The site carries display advertising. Advertisements are supplied by third parties, their content is not ours, and an advertisement is not an endorsement — least of all of any tutoring service, degree programme, essay service or lender that may appear in one. See the privacy policy for the data side of that.
Content and reuse
The text, the explanations, the worked examples and the arrangement of this site are ours. The underlying facts — that 93% is an A, that an A− is 3.7 grade points, that a weighted average is the sum of the products over the sum of the weights — are facts and belong to nobody. Quote a figure or a band freely; please do not copy the pages.
Ages
This site is written for high school and college students and for the people who teach them. It is not directed at children under 13. Nothing on it requires an account, an email address or any personal information, from anyone of any age.
