Remember what you study
GRANIT is spaced repetition for maths and other demanding subjects. Write cards with real equations, and GRANIT brings each one back just before you would forget it.
GRANIT online is by invitation: open the link you were sent to make your account.
Fill in the blank
If f(x) = \sin x^2, then f'(x) = […].
If f(x) = \sin x^2, then f'(x) = 2x \cos x^2.
Equations as you'd write them
Type maths the way Word does: a/b turns into a fraction as you go. No code to learn.
Each card at the right moment
The FSRS scheduler works out when you'd start to forget each card, so a few minutes a day keeps it all fresh.
See where you stand
Today shows what's due, and the map shows your topics and how firmly you know each one.
