What's in a lab?

1
Read the objective. Each lab opens with a clear goal — one real RHCSA exam skill per lab.
2
Work through steps. A guided Steps panel walks you through each task in sequence, with hints and explanations.
3
Type real commands. The browser terminal simulates a RHEL environment — no install, no VM, no setup.
4
Get validated. Requirements tick off automatically as you complete them. Confetti fires when you're done.

Each lab takes 10–20 minutes. Progress saves automatically in your browser.
