Create a one-page cheat sheet for something you're learning

Make a one-page cheat sheet.

Topic: [details]
My notes: [paste]
Must fit: [one page / index card]
I will use it for: [practice / open-book / revision — not closed-book cheating]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A dense one-page layout.
2. Formulas or phrases to highlight.
3. Common mistakes section.
4. What to blank out to test myself.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, steps or official URLs you're not sure of. UK English.
