Branch, merge, rebase, and undo with confidence

Master version control with Git — the working-directory/staging/repo model, commits and branches, merge vs rebase (and when to use each), resolving conflicts, the remotes workflow (fetch/pull/push), and undoing/recovering work (reset vs revert, reflog, stash, cherry-pick). Concept and command-behavior questions that build real day-to-day Git fluency. Part of the Developer track.

• Meets you at your level — never too easy, never too hard.

• Adapts every question to how you’re doing.

• Tracks your level over time. Skill practice, not a test.
