Spaced repetition works. Decades of evidence say that reviewing material at widening intervals beats cramming, by a wide margin. But the classic flashcard deck flattens a subject into thousands of unconnected cards, and review becomes a queue with no sense of structure.

Review that follows the map

Because LMNTS knows the prerequisite graph, review can respect it. When a foundational concept starts to fade, everything built on top of it is at risk too — so it surfaces first. You reinforce the root before the branches, and a single well-timed review steadies a whole region of the map.

Recursion is fading. Review today.

The result reads less like a chore queue and more like a journal that keeps itself current: it flags what's slipping, points you at the highest-leverage review, and quietly records the proof as you go.
