Your five weekly sessions are shared across these six scenarios. Use them to try different topics or repeat a task. Each session gives you 12 minutes once the environment is ready. Your allowance resets every Monday at 00:00 UTC.
Hints, solutions, grading, saved progress and AI Lab Coach are included. In a lab, open the coach tab and request a diagnosis of your commands, saved files and current lab state. Provisioning failures do not use a session. Read the briefs on any device; use a desktop or laptop for the terminal lab.
