GradeCat is a set of eight free tools for grades, GPA and grading scales, with guides to go with them. You do not need an account, and your grades stay in your browser.
Why we made it
Your grade depends on your school's rule, and the rule changes from one country and one school to the next. Even inside one country it varies: the US has no national grading standard:
- A 92 is an A under Florida law for public school grades 6-12. It is an A- in the Johns Hopkins School of Nursing.
- An A- is worth 3.7 grade points at the University of Missouri and 3.67 at the University of Illinois.
- An A+ is worth 4.0 at UC Berkeley, 4.3 at Cornell and 4.33 at the University of Iowa.
So our tools let you choose the rule, show which rule a result uses, and link to where that rule comes from.
