The free diagnostic scores you by domain so you know exactly what to practice for GH-300.
No. Every question is original, written to the official GitHub Copilot exam objectives. We never use exam dumps or leaked questions, which violate certification agreements and can get candidates banned. The goal is to teach the concept the exam tests, not to memorize a specific item.
Are the GH-300 practice questions free?
Yes, these samples are free with no signup. The free readiness diagnostic then scores you across every domain so you know exactly which objectives to study first.
Do the questions come with explanations?
Yes. Every question includes an explanation that teaches the underlying concept and why the other options are wrong, so a practice set actually moves your score.
Will practice questions get me GH-300-ready?
Practice is one part. Combine it with the diagnostic (to find your gaps) and timed mock exams (to test pacing), then use your readiness score to decide when to book. Walk in prepared, not hopeful.
