Master Git and GitHub with the most comprehensive practice test collection available — 600 carefully written multiple-choice questions spanning everything from foundational commands to advanced internals and CI/CD automation. Whether you're a fresher preparing for your first technical interview or an experienced engineer brushing up before a senior-level round, this course is built to meet you where you are.

This course puts you through six focused practice tests, each targeting a distinct area of real-world Git and GitHub usage:

Git Fundamentals & Setup — repository basics, staging, commits, configuration, SSH authentication, and .gitignore
Branching & Merging — branch management, merge strategies, conflict resolution, and fast-forward vs. three-way merges
Remote Repositories & GitHub Collaboration — forks, pull requests, code review, branch protection, GitHub CLI, and repository administration
Advanced Git — interactive rebase, cherry-picking, stashing, reflog recovery, bisect, tagging, and submodules
Git Internals & Hooks — the object database, packfiles, plumbing commands, hooks, and transport protocols
GitHub Actions, CI/CD & Team Workflows — workflow syntax, matrix builds, deployment strategies, semantic versioning, and security best practices

Every single question includes a detailed explanation for each answer option — not just the correct one — so you understand exactly why each choice is right or wrong. Here's a sample of what you'll get:

Q: What is the key difference between git init and git clone?
A. git init creates a brand-new empty repository, while git clone copies an existing remote repository (with its full history) to your machine . Correct — this is exactly what distinguishes the two commands.
B. git clone creates new history, while git init copies existing history — This reverses the actual roles: git init creates new, git clone copies existing, not the other way around.
C. Both commands only work with GitHub — Both work with any Git remote (or purely locally); neither is GitHub-specific.
D. There is no real difference between them — There is a clear functional difference: one creates new history, the other copies existing history.

That's the depth of explanation behind all 600 questions — no vague "all of the above" traps, and answer choices evenly balanced across A/B/C/D so you can't game the test by pattern-matching.

By the end of this course, you'll have a rock-solid command of Git's command-line workflow, GitHub's collaboration features, and modern CI/CD practices with GitHub Actions — the exact skills technical interviewers look for at every experience level, from your first job to your next promotion.

No prior Git experience is strictly required, though basic command-line familiarity will help you get the most out of the advanced tests.
