Spaced repetition
Review formulas after 1, 3, 7 and 14 days. The brain stores what is repeated at intervals.

Write the formula by hand 5 times. Motor memory reinforces visual memory.

Teach someone else
Explain to a friend. Where you stumble — that is the gap in your knowledge.
It is not knowledge, but the act of learning which grants the greatest enjoyment.
— Carl Friedrich Gauss (1777–1855)
