Twelve questions on core Git behavior — staging, branching, remotes, and undoing changes — each grounded in the official Git documentation. Your score shows which of these questions you answered correctly; it does not certify a skill level.

What the HTTP specification actually says about methods, status codes, caching and representations.

How the base units are defined since the 2019 redefinition, and how unit symbols must be written.

Three-valued logic, outer joins and aggregate behaviour, as defined by PostgreSQL 18.

Twelve questions across selectors and specificity, the box model, the cascade and inheritance, and basic layout, focused on the rules people most often get wrong when they build their first real layouts. The result is an indication of which of those four areas you currently answer confidently and where reviewing would pay off — it is an orientation aid, not a measurement of your ability and not a verdict on any particular project or job.

Twelve questions on widely accepted practices in feedback, meetings, written and asynchronous communication, and difficult conversations. The result is an indication of how familiar you are with these practices, not a diagnosis of how you communicate at work and not an assessment of you as a person.

Twelve questions about the planet you live on: capitals that were built from scratch, lakes with no bottom in sight, and a few borders that refuse to behave. It is a quiz for fun — the score at the end is a scoreboard, not an assessment of anything.
