XP is Math Ladder AI's measure of work completed — not time spent staring at the screen.
Every task is calibrated so its XP roughly equals the minutes of focused effort it takes a well-placed student. A 12 XP lesson is about 12 minutes of real work. That makes XP comparable across everything: lessons, reviews, quizzes, and exam sections.
| Lesson | 6–20 XP, scaled by the topic's difficulty — a limits lesson pays more than a times-tables refresher because it takes longer to do well. |
| Review | 4 XP per topic, up to three topics interleaved in one task. Reviews are short by design — the spacing does the heavy lifting. |
| Quiz | 10 XP after every six lessons, covering recent material. |
| Exam section | 15–40 XP for timed AP, PSAT, SAT, ACT and AMC 8 mock sections. |
Completing a lesson always pays its XP — the work happened. But the topic is only mastered at 75% or better on its practice, and only mastery unlocks what's built on top. So you can't XP-grind your way past understanding: XP measures the walking, the knowledge graph measures the ground actually covered.
Because review credit trickles down prerequisite edges (working a hard integral is practice of the algebra inside it), you're never asked to spend XP-minutes reviewing something you just used inside a harder problem. Nearly every XP you earn is spent at your learning frontier — which is why a steady 30 XP/day compounds so quickly.
You (or a supervising adult) set an XP goal for each day of the week in Settings. Hitting every scheduled day extends your streak; days set to 0 XP are rest days and never break it. The weekly total drives your estimated course-completion date — at 150 XP/week, the dashboard shows exactly when your course lands.
