GH-300 Practice Exams 2026: GitHub Copilot Certification

Six full GH-300 practice exams with 60 questions each, 360 original questions in total. Every test runs 100 minutes, the length of the real exam.

BUILT ON THE AUGUST 2026 SKILLS OUTLINE

Microsoft updated the GH-300 skills measured on 7 August 2026, and every question follows that version. Material written against an older outline may miss some of the newer details.

SIX TESTS THAT GROW WITH YOU

Test 1 shows where you stand, and Test 4 is a full simulation at exam level. Tests 5 and 6 go above it: each scenario gives you more facts to weigh at once, and more questions link two areas of the exam.

Pass Test 6 with confidence and you walk into the exam with a margin. The pass mark climbs from 60 percent in Test 1 to 80 percent in Test 6.

From Test 1 on, the questions are scenario-based in the style of the exam, so the reading load on exam day feels familiar. Most ask for one answer, and some ask you to pick two or three.

Microsoft reports a scaled score with 700 as the pass mark. The percentages in this course are a setting I chose for each test and are no conversion of that score.

AN EXPLANATION FOR EVERY OPTION

After each test you see why the right answer is right and why each wrong option fails in that specific scenario. Every explanation names the official domain and objective group behind the question.

THE SIX EXAM DOMAINS

Each question belongs to one official domain, so your results show where you still need work. Across all tests the questions follow Microsoft's weighting:

• Use GitHub Copilot responsibly (15 to 20 percent)

• Use GitHub Copilot features (25 to 30 percent)

• Understand GitHub Copilot data and architecture (10 to 15 percent)

• Apply prompt engineering and context crafting (10 to 15 percent)

• Improve developer productivity with GitHub Copilot (10 to 15 percent)

• Configure privacy, content exclusions, and safeguards (10 to 15 percent)

WHAT YOU WILL PRACTICE

Inline and next edit suggestions, Copilot Chat modes, agent mode and Copilot CLI with its permissions and hooks. Copilot code review, cloud agent, Copilot Spaces and MCP servers.

On the admin side you work with organization and enterprise policies, seat management, the audit log, content exclusions and the public code filter.

HOW TO START

Take Test 1 without preparing for it and treat your score as your starting point. Then read the explanations for the domains where you lost points before you move on to Test 2.
