PracticeCalculus teaches calculus the way you actually learn it: by solving problems. Each lesson is one small idea, two or three sentences and a worked example, followed straight away by practice. You type real answers (derivatives, limits, integrals, vectors) with a built-in math keyboard. When you slip, PracticeCalculus points to the exact mistake, offers hints, and replays the solution step by step. All of Calculus 1 is free, plus the first units of Calculus 2 and 3. Pro unlocks the rest.

Hi Fazier! I built PracticeCalculus so learning calculus feels like doing it, not watching it. Every lesson is one small idea and a worked example, then you solve problems yourself with a math keyboard. When an answer is wrong, it points to the exact step that went off and replays the solution. All of Calculus 1 is free. I'd love blunt feedback, especially from anyone who's taught or recently taken calculus.
