What Are Cheat Sheets and How to Use Them

Cheat sheets are one-page visual summaries of each chapter’s key content — formulas, definitions, diagrams, and core concepts condensed into a single reference sheet.

They are useful for quick review before an exam, checking you have covered all key points in a chapter, and as a reference while doing practice questions.

Access cheat sheets from any chapter page or from the subject page under “Cheat Sheets.” You can view them on screen or print them.
