Cheatsheets
These cheatsheets are built for the final hour before GH-300: dense, current, and deliberately limited to facts that can be checked against GitHub or Microsoft documentation.
Every card in this section is verified against official documentation before publication. If a shortcut, slash command, plan feature, billing unit, or model name cannot be confirmed against a GitHub or Microsoft source, it does not make the card.

What is here#
Use the pocket card when you need the current answers fast: chat modes, VS Code slash commands, chat variables, participants, keyboard shortcuts, plan features, AI Credits, content exclusions, customization paths, and the six exam domains.
Verify shortcuts against your own IDE
Keyboard shortcuts differ between VS Code, Visual Studio, JetBrains, Eclipse and Xcode, and so do some slash commands. The pocket card lists the VS Code bindings that appear in GitHub's keyboard shortcuts reference. If you sit the exam expecting a shortcut from a different editor, it will not match.

How to use it#
Scan the tables in the order the exam weights them: chat modes and features first, then privacy and exclusions, then prompting. GH-300 turns on precise product-behavior details, so the specifics — which plan, which scope, which file path — are what repay memorizing.
