Many older GitHub Foundations prep sets predate Microsoft Learn's January 2026 GH-900 study-guide refresh — missing critical 2026 exam topics like GitHub Copilot coding agent (asynchronous cloud agent on Issues opening draft Pull Requests in an isolated GitHub Actions environment) versus local IDE Agent Mode, Copilot multi-model selection, `.github/copilot-instructions` and Model Context Protocol (MCP) servers, Copilot Free/Pro/Pro+ vs Business ($19, no GHEC required) vs Enterprise ($39, Knowledge Bases on GHEC), WebAuthn Passkeys, Repository Rulesets (`Evaluate` dry-run mode), Enterprise Managed Users (EMUs) on GHEC  data residency, and GitHub Projects v2 (`Table`, `Board`, `Roadmap`, `Iteration` fields, and `Burn up` Insights).

Passing Exam GH-900 requires crisp conceptual precision under a closed-book 100-minute clock: separating Git (local distributed VCS snapshots, staging index, branches, `fetch` vs `pull`) from GitHub's cloud collaboration platform; choosing Personal (`Free`/`Pro`) vs Organization (`Team`) vs Enterprise (`GHEC`/`GHES`) accounts; practicing GitHub Flow and GFM Markdown (`- [ ]`, `> [!NOTE]`, Mermaid, `/` slash commands); configuring `README`, `LICENSE` (no license = all rights reserved!), `CONTRIBUTING`, `SECURITY`, `.gitignore`, and `CODEOWNERS`; choosing Template repositories over Forks; managing Issues, Draft PRs, `Closes #N` links, YAML Issue Forms, Discussions, Watch levels, Secret Gists (unlisted, NOT private!), Wikis, and GitHub Pages; comparing GitHub Codespaces (`.devcontainer/devcontainer.json`) against zero-compute `github dev` (`.` shortcut); planning sprints in GitHub Projects; enforcing 2FA recovery codes, Passkeys, the 5 Repository Roles (`Read`, `Triage`, `Write`, `Maintain`, `Admin`), `Public`/`Private`/`Internal` visibility, Rulesets, and EMUs; and leveraging GitHub Sponsors (`0%` personal fee), Marketplace Apps vs Actions, and InnerSource.

This course delivers 600 original, Fundamentals-calibrated questions across 6 full-length mock exams of 100 questions each, weighted strictly to Microsoft's official January 2026 GH-900 study guide:

• Understand Git and GitHub basics (25–30% -> 28 questions per exam; 168 total)

• Work with GitHub repositories (10–15% -> 14 questions per exam; 84 total)

• Collaborate using GitHub (10–15% -> 14 questions per exam; 84 total)

• Apply modern development practices (10–15% -> 14 questions per exam; 84 total)

• Manage projects with GitHub (5–10% -> 8 questions per exam; 48 total)

• Understand privacy, security, and administration (10–15% -> 14 questions per exam; 84 total)

• Explore the GitHub community (5–10% -> 8 questions per exam; 48 total)

ABOUT EXAM GH-900 & GITHUB EXAM RULES

Earning the GitHub Foundations certification requires no prior certification, costs $99 USD via Pearson VUE, and never expires — it does not require renewal. Unlike Associate/Expert Azure exams, GH-900 is strictly closed-book (split-screen Microsoft Learn access is NOT available on Fundamentals exams or GitHub exams) and gives 100 minutes of exam time (120 minutes total seat duration) with standalone questions only — zero multi-tabbed case studies and zero live labs.

REALISTIC GH-900 QUESTION PATTERNS (WITHIN UDEMY CSV LIMITS)

• CLI, Markdown, Search & Config Slot Completions (____): 20–21 items per exam (124 total) testing `git` commands (`fetch`, `restore --staged`, `stash`, `revert`, `blame`), GFM alerts, `Closes #N`, search qualifiers (`is:pr draft:true`, `no:assignee`, `iteration:@current`), `.github/workflows/`, `CODEOWNERS`, `FUNDING.yml`, and keyboard shortcuts (`.`, `t`, `y`)

• Proposed Solution Evaluations: 6–7 items per exam (39 total) exposing classic GitHub traps (storing API keys in Secret Gists, trying to run bash/Docker in browser-only `github dev`, committing `CODEOWNERS` without branch protection, adding `.gitignore` without `git rm --cached`, Forking instead of `Use this template`, expecting personal Saved replies to share org-wide, or trying to push public OSS repos from an EMU account)

• Ordered 4-Step Sequences (->): 8 items per exam rehearsing local Git staging/pushing, GitHub Flow, `CODEOWNERS` enforcement, Issue-to-PR auto-closing, GitHub Pages, GitHub Actions CI, Codespaces devcontainers, GitHub Projects automation, 2FA + Passkeys, and open-source Fork-and-PR workflows

• Multi-Select Scenarios: 16 Select-two / Select-three items per exam (13 five-option `Select two.` + 3 six-option `Select three.`) with explicit selection counts

• Zero Artificial Case Studies: Every question is self-contained across 6 distinct organizational themes, matching the live GH-900 exam format

WHAT EVERY QUESTION INCLUDES

• Detailed per-option explanations on all 4–6 choices clarifying why each keyed answer fits and why every distractor fails

• Concise overall synthesis mapped to all 36 official January 2026 GH-900 skills (`1.1` through `7.6`) with direct `docs.github`  links

HONEST PACING & PLATFORM BOUNDARIES

The live GH-900 exam provides generous 100-minute exam timing (~60 seconds per item on a 100-question mock exam!). Set a 100-minute closed-book timer on each exam to match live exam conditions, or a 75-minute timer for rapid recall mastery. Practice percentages do not convert directly to Microsoft's 700 / 1000 scaled score, and interactive Pearson VUE drag-and-drop / dropdown / Yes-No grid widgets are adapted into text-complete CSV questions.
