How GradeMate works
Three steps. No sign-up. Always under a minute.
1. Pick your calculator
Whether you're tracking a semester grade or estimating your AP Bio score, choose one of the eight calculators above. They're grouped by what you're tackling — classroom grades on one side, big-test predictions on the other.
2. Enter your numbers
Type in what you know — how many multiple-choice questions you got right, your homework average, the weight of your final, whatever the calculator asks. Everything stays in your browser; nothing ever uploads.
3. Get your answer (and what to do next)
You'll see your predicted grade, score, or GPA right away. Most calculators also show what you'd need to bump up a letter or score band — so you know exactly where to focus next.
What's a grade calculator (and which one should you use)?
A grade calculator does the math you'd otherwise do on the back of a Calc test page — it tells you what grade you're sitting at, what you need on the next assignment to climb up, or how a tough final will shift your overall standing. The right calculator depends on what you're trying to figure out.
For your classroom grade
If your teacher posts grades by category — homework, quizzes, exams, projects — use the Weighted Grade Calculator. If you just want to know how the final will move your average, use the Final Grade Calculator. For semester GPA tracking on the 4.0 or 5.0 scale, the GPA Calculator handles both unweighted and weighted.
For your big standardized exam
AP, SAT, and ACT scoring is different from classroom math. You don't get a percentage; you get a curved score (1–5 for AP, 400–1600 for SAT, 1–36 for ACT). Our AP Score Calculator, SAT Score Calculator, and ACT Score Calculator convert your practice-test raw scores into the actual scoring scale colleges see — using the most recent publicly available scoring curves.
Not sure which one fits your situation? Start with the calculator named for what you're trying to do — Final Grade for finals week, AP Score for AP prep, GPA for college applications. All eight run instantly with no sign-up.
Why students trust GradeMate
Built by people who remember finals week. Designed around what students actually need.
Sources, not vibes
Every score calculator cites the College Board or ACT scoring guide it's calibrated against. You can click through and verify the cutoffs yourself — no black-box predictions.
Nothing leaves your browser
Your grades, your scores, your inputs — they all stay on your device. No accounts, no tracking pixels, no data sales. Ever.
Updated every year
AP scoring curves shift a little each year. We use released College Board scoring worksheets directly when they match the current exam structure, and keep estimated subjects clearly labeled as previews.
Free forever, ad-supported
Unobtrusive ads around the page keep this free for every student. Ads never go inside the calculators — we won't break your workflow to chase a click.
Frequently asked questions
What students ask most before using a score calculator.
What is GradeMate?
GradeMate is a free, no-sign-up suite of grade and test score calculators for U.S. students — covering classroom grades, GPA, and standardized exams (AP, SAT, ACT). Everything runs in your browser; your inputs never leave your device.
How do I use the AP Score Calculator?
Pick your AP subject, enter how many multiple-choice questions you got right, and your estimated points on each free-response question. The calculator returns a predicted 1–5 score and tells you how many more points you'd need to reach the next band.
Are the score curves official?
Some AP calculators use official released College Board worksheet data when the public worksheet matches the current exam structure. Subjects without a matching worksheet, plus SAT and ACT, stay clearly labeled as estimates or unofficial previews. Each calculator lists its sources so you can verify.
Is GradeMate really free?
Yes. The site is funded by unobtrusive ads placed around — never inside — the calculators. We do not sell your data and never will.
What's coming next?
More AP subjects (we cover all major ones at launch), IELTS / GRE / MCAT estimators, and a 'save my goals' feature for students preparing across multiple exams.
