The GH-900 practice test prepares you in foundational Git, GitHub workflows, collaboration, automation, and security concepts within the GitHub ecosystem.

Why should I take the GH-900 exam?

The GH-900 certification validates your competence in essential GitHub skills: using version control (commits, branches, merges), managing repositories (cloning, pushing, forking), collaborating through issues, pull requests, and code review, and setting up basic GitHub Actions workflows. It also covers repository and organization security fundamentals: permissions, branch protections, and dependency/security features, plus how GitHub integrates with project planning and community capabilities. GH-900 demonstrates you can confidently participate in real-world collaborative development on GitHub and provides a strong baseline if you later pursue other Microsoft/GitHub certifications.

The GH-900 practice test includes two different modes: certification and practice mode. Certification mode allows you to assess your knowledge and discover your weak areas, with practice mode allowing you to focus on the areas that need development.

The GH-900 practice test contains 100 questions and covers the following objectives:

• Domain 1: Introduction to Git and GitHub - 22 questions
• Domain 2: Working with GitHub Repositories - 8 questions
• Domain 3: Collaboration Features - 30 questions
