• Self-Audit Checklist — a one-page checklist covering all six chapters, so you can run any screen you’re designing through the same standards the book teaches.

• Critique Exercise — a realistic (but flawed) interface, six guided questions, and a full walkthrough explaining what’s wrong and how to fix it.

• Decision Guides — five quick-reference flowcharts for the judgment calls that come up most often, the ones where the “right” answer genuinely depends on context.
