GH-900 How to Prepare
Study Resources
GitHub provides free learning paths through Microsoft Learn and the GitHub Skills interactive courses. The official study guides outline exactly which features and workflows are tested. Hands-on experience with GitHub repositories, Actions, and security features is essential.
Preparation Strategy
Start by reviewing the official exam guide to understand exactly what's covered. Allocate your study time proportionally to domain weights: spend the most time on Understand Git and GitHub Basics (28%) and work down from there. Most candidates need six to twelve weeks of focused preparation depending on their existing experience.
Hands-On Practice
Reading alone won't get you through this exam. You need hands-on experience with the technology. Set up a lab environment, work through practical scenarios, and practice until the concepts feel natural. The exam tests application of knowledge, not just recall.
GH-900 Exam Day Strategy
Time Management
With 1 minute and 28 seconds per question, pace yourself from the start. Don't spend more than three minutes on any single question during your first pass. Flag uncertain questions and return to them after completing the rest. A wrong answer and a skipped answer score the same, so never leave a question blank.
Reading Questions Carefully
Pay close attention to qualifier words like "most," "best," "least," and "first." These words change the correct answer entirely. Read every option before selecting your answer, even if the first option looks correct. Exam writers intentionally place plausible distractors early in the option list.
