This calculator is 100% free to use. It works like the calculators students see on these exams, but it is not the same tool. The official testing calculators turn off certain features, some tests ban advanced models with a computer algebra system, and the rules differ by test and section. Always practice with the exact calculator allowed on your exam, and confirm the current policy on your test's official website.
Our certified tutors teach the calculator skills that show up on the SAT, ACT, AP exams, and NJ state tests, from the fastest keystrokes to the graphing moves that save time under pressure. Every tutor is background-checked.
