How labs are graded

Most certificates prove you watched the videos. Ours prove your code runs — AI-assisted to build, held-out to verify.

The pass rule

Every lab is auto-graded on running code: it passes only when both companion scripts exit cleanly on your solution — not quizzes, not completion.

That's the whole bar: not a multiple-choice quiz, not a “mark complete” button — your code has to actually run and pass. It's the same signal a job interview cares about.

Two kinds of lab

Guided lab

AI-assisted, with Claude Code, hints, and a per-step answer reveal — so you can't get stuck. Auto-graded on running code. This is the standard lab — you can’t get stuck, and it’s still graded on running code.

Verified checkpoint

Beta

A held-out checkpoint is in early beta: a held-out problem, server-graded on hidden tests with no AI pair-programmer — a problem the course didn’t walk you through, solved with the AI pair-programmer switched off. No credential is issued yet: no profile shows a Verified badge.

Working a lab

Every passed lab becomes a signed node on your skill graph — a recruiter-auditable record of the labs you actually passed.
