What you take away
- Every class has the same shape: predict, the simple version, the precise version, the real world, a quiz and cards.
- Saying how sure you are before you see the answer trains calibration: knowing when to trust yourself.
- Review cards come back right before you would forget them; about 5 minutes a day keeps what you learned.
- Each sidebar section has one job, and Today puts your 15 to 25 minutes together for you.
- The tutor in each class gives hints before answers, on purpose.
