A one-page reference card for every lesson — memorise one-liners, interview traps, and quick-reference tables. These are the artifacts to reprint the morning of your round.
How to use these. Open the sheet, cover the right-hand column, and recite each one-liner from memory. If you hesitate, that's your signal to re-read the lesson. Every sheet prints cleanly on dark — hit ⌘P and the background is preserved.
