Labs

Rooms ask you questions. Labs hand you the parts. Each one is a chain of steps where you build something, test it, break it, and only move on once it works.

Labs are new, and still being smoothed out — expect the occasional rough edge as more of them ship. The marking underneath is exact regardless: if a board says it works, it works. Spot something odd? Give feedback from the account menu.

On the bench

Being built. Same shape, different subject.

How a GPU works

Spot the phish

Read real headers, follow real links, decide what is safe.

Chemistry lab

Push something and watch the numbers already know what happens.

Math lab

Build a proof the way you would build anything else — one true step at a time.

Machine learning lab

Teach a machine by handing it examples, not rules.
