Before you start

This measures you, with the AI off. No assistant, no autocomplete, no looking things up — if you reach for help, you get a number that isn’t yours, and the honest read at the end will be wrong.

A quick warm-up, then 3 short drills — one sitting, about 14 minutes. Each has its own timer; when it runs out, it moves on, so trust your first read. No going back.

A couple are meant to make you think — that’s the point, not a verdict. You start with an easy win and get a per-skill read at the end.

Language for this read

Pick the language you actually work in — this should measure decay, not unfamiliarity.
