Watch the idea move. Then prove you understand it.
50 AP Calculus AB/BC questions, each paired with a short animation that shows the calculus happening — a tangent line sliding, rectangles filling in an area, a series converging. Answer correctly and the questions get harder. Miss one and they ease back. Reach 100 points to win, or the clock decides for you.

How scoring works: Every correct answer adds points (harder questions are worth more) and nudges the next question up a difficulty step. A wrong answer keeps your score the same and drops the next question one step easier, so you're always working near your edge.
How it ends: The instant your score reaches 100, the quest ends and your certificate appears. If your timer runs out first, the quest ends immediately with whatever score you've earned.
