Daily mastery

Make the methods stay with you.

Answer up to five focused questions chosen from assessments you have already completed. Strong concepts wait longer; weaker ones return sooner.

Retrieval practice

Up to five questions, selected from work you have finished

Daily Mastery Review uses short, spaced practice to revisit completed quiz, true/false, multiple-select, numeric, and fill-in-the-blank assessments. It never needs the in-browser Python runtime and it never awards course points.

  • Hints are optional and clearly marked.
  • Your answers stay on this device when you are signed out.
  • When you sign in, mastery can follow your account.

The review loop

A small habit with a precise purpose

  1. 01

    Retrieve

    Recall the idea without rerunning a lesson or opening a notebook.

  2. 02

    Correct

    Use a hint when needed, then read the explanation while the decision is fresh.

  3. 03

    Return

    The scheduler brings weak concepts back sooner and gives strong concepts more space.
