Spaced repetition works better with real prompts

Rereading feels fluent because the page gives you the answer. Recall feels harder because your brain has to produce it.

The main idea

Write prompts that make you retrieve a method, not just a definition.

A short example

Instead of 'Projectile motion formulas', ask 'How do I find time of flight when launch and landing height match?'

Check while you solve

• Review after a delay.
• Answer before looking.
• Mark prompts as easy, shaky, or missed.
