What it does
Mastery, not completion
Score below 80% on a topic and it stays in your queue. No skipping ahead with a half-understood foundation.
A different angle
When you miss a question, the AI re-explains the concept from a different angle and gives you a parallel problem to try.
Spaced repetition
Your topic queue follows the FSRS algorithm. Items return on the days research says you're about to forget them.
