Prepare for the GH-300 exam (GitHub Copilot certification). In this lesson: generating code, from boilerplate to agent mode, refactoring and documenting, commit messages and pull request summaries, learning with /explain and less context switching, sample data without real personal data, and modernizing legacy code step by step, with tests. Includes three original practice questions.
