I found the best way to study with Claude

A flashcard deck that grades itself and remembers what I missed. Spaced repetition without opening another app
Clicking through a concept beats reading about it. Step-through diagrams for anything with a sequence
Dragging a slider taught me supply and demand faster than a textbook. Simulations for the «it depends on X» problem
How the /learn skill decides to build instead of explain. The trigger conditions that actually matter
