GH-300 GitHub Copilot: 6 Practice Exams (600 Qs)

About this course

Many GitHub Copilot practice tests still target the pre-August 2026 7-domain blueprint (where Responsible AI was only 7% and CLI questions tested the legacy `gh copilot suggest` / `gh copilot explain` GitHub CLI extension). Effective August 7, 2026 (study guide updated July 9, 2026), Microsoft Learn overhauled Exam GH-300 into a 6-domain, 41-skill blueprint elevating Responsible AI to 15–20% and testing the modern agentic Copilot ecosystem: the standalone GitHub Copilot CLI (`@github/copilot` on Node.js 22+, Homebrew, or Win

Get), VS Code Agent Mode, Copilot Edits, Next Edit Suggestions (`NES`), Model Context Protocol (`MCP` via `.vscode/mcp.json`), unified Agent Sessions, context-isolated `#run

Subagent` subagents, the asynchronous cloud Copilot coding agent (`@copilot` draft PRs), Copilot Spaces, GitHub Spark micro-apps, Automatic Copilot Code Review rulesets (`Review new pushes`, `Review draft pull requests`), modular `.github/instructions/*.instructions md` (`apply

To:` + `exclude

Agent:`), reusable `.github/prompts/*.prompt md` slash templates, Enterprise `AI controls -> Agents` overrides, and `CodeQL` Copilot Autofix.
