Use your notesUnderstand the method
Read definitions, assumptions, and a complete worked example. Best when you need to understand why a step works.
Build a reviewerRecall without looking
Test one definition or step at a time. Mark what still needs practice and use Learn for a focused round.
Make useful cardsApply the whole lesson
Answer a set before checking feedback. Use missed questions to find which explanation or procedure to revisit.
Prepare an examOne lesson, three passes
This is a starting schedule, not a built-in timer. Adjust it when a problem needs more time.
Bring readable source text, choose one format, and check the result in the editor. Generation depends on setup and allowance; manual creation is always a separate route.
Prepare your sourcesKeep sketches beside your text, then choose a direct reviewer or an AI draft from one page or a whole notebook.
Choose source text, set the format and question mix, then review the result before anything is published.
A practical review pass for source accuracy, calculations, answer choices, and privacy.
Use known cards, stars, and repeat practice for different purposes, and understand what your saved progress actually records.
Use flags during an attempt, inspect worked solutions after submission, and turn the result into a specific next study step.
