Validates foundational knowledge of Git and GitHub, including repositories, collaboration, project management, automation, security and administration.
GH-900 is closed book: 100 minutes for 60 scored multiple-choice questions plus about 10 to 15 pretest items. It tests GitHub the product more than Git: plans, roles and permissions, where features live, and Copilot, Actions and security basics, often as select-all questions. We compared the main options on question style, question volume and price.
Start with Microsoft's free practice assessment and GHCertified's 147 free questions; a paid bank is optional if you want more volume or timed runs.

Microsoft's own practice questions, with the answer, a rationale and doc links for each question in the score report. Candidates find the real exam harder, and one answer in it has been disputed.
Great fit if you want Microsoft's own question style and a free baseline before spending anything.
Poor fit if you want volume or select-all practice at exam difficulty; add GHCertified or a paid bank.
Community-written questions kept in an open GitHub repository, in a randomized practice mode that links to the GitHub docs. It has the largest free bank for this exam.
Great fit if you want a large free set on roles, plans and features after the Microsoft assessment.
Poor fit if you want written explanations or a timed full-length run; use Krausen's exams or Tutorials Dojo.
Four 60-question exams with an explanation of every option and links to GitHub's docs. It is the best-rated paid set, though it was last updated in December 2025, before the outline changed.
Great fit if you want several full-length runs from a well-rated set and can pick it up on a Udemy sale.
Poor fit if you want questions mapped to the January 2026 outline; use MeasureUp.
A question bank with explanations and links to Microsoft docs, in randomized, timed, review and section modes, with seven section quizzes and flashcards. A free 30-question sampler lets you try it first.
Great fit if you want a low-cost bank with quizzes by domain and want to try a free sampler first.
Poor fit if you want a larger set; Krausen has twice as many questions.
Timed certification mode and a customizable practice mode, with explanations and online references for every option. The page lists an August 2026 update, and a free demo and some free questions are available.
Great fit if you want a recently updated paid bank with explanations and references, or your employer is paying.
Poor fit if you are paying yourself; the exam costs the same $99 and the free sets plus Tutorials Dojo are enough for most candidates.

Yes. Microsoft Learn has a free practice assessment (sign in with a Microsoft account), GHCertified has 147 free community questions, and Tutorials Dojo offers a free 30-question sampler. Microsoft's exam sandbox also lets you try the exam interface.
Candidates say the real exam is harder than Microsoft's assessment, mainly because it asks about plans, roles and features the course covers lightly. The free sets are best used to find weak domains.
There is no official number. Most passers in Reddit threads used the Microsoft assessment plus one more bank, and reviewed GitHub's docs for every miss rather than retaking the same set.
Yes. Candidates report many choose-two or choose-three items alongside single-answer questions, so practise multiple-response questions with explanations for each option.
