Flashcards
Recall beats rereading. Every chapter in the sixteen volumes has cards: its central idea, and each of its exercises with the solution on the back, 1,192 cards in all. A chapter's cards join your deck when you mark it read. Say how well you knew each answer and the card comes back just before you would forget it.
Your deck
Chapters marked with a dot are in your deck. Add any chapter to start learning it before you read it, or study one chapter on its own; studying a chapter adds it. A card you know moves up a box and waits longer, 1, 3, 7, 16, 35 then 80 days; one you miss goes back to the first box. At most 20 new cards a day, so reviews never pile up. Your schedule is saved in this browser and, when you're signed in to Claude, in your account, so it follows you between devices.
