How courses work

How each step works
  • Short lessonsA few minutes each, so a lesson fits between other things.
  • Marked answersMost answers are marked straight away, and you see why. Longer written answers you mark yourself, with the mark scheme beside them.
  • Streaks and SparksA lesson, some flashcards or a focus block counts for the day, and a rest day keeps your streak going once a week. A Spark opens a helper beside a question: 3 a day, or 5 with a free account.
  • Free and PlusThe first lessons of every course are free. Brainlag Plus opens the rest.
