01
Understand the task
Short explanations, supplied facts and local documentation.
-
02
Make the system work
Stateful exercises with files, services and saved configuration.
-
03
Verify. Then revisit.
Check the result, practise a different variant and try a real-machine guide.
03 / LESS WATCHING. MORE DOING.
Make it run.
Make it stick.
A small taste of state-based practice. Starting a service and keeping it running after reboot are two different things.
A tiny teaching simulation. Nothing executes on your machine.

Three checks. More than one valid approach.
This website demo supports only the commands listed above. The app’s labs represent more state and declare their own limits. Neither is a complete Linux runtime.
04 / MAKE IT YOURS
A little more play.
The same real practice.
Keep the focused experience you know. Or give your practice a new sense of adventure.
Familiar. Focused. Yours.
Your existing Today screen, practice flow, ranks and badges. Classic stays the default when you update.
- Jump straight into a useful session
- Keep your progress and earned access
- Switch to Adventure whenever you like
One progress history. One purchase. No starting over.
05 / SMALL SESSIONS. USEFUL OUTCOMES.
Built for the
way skills grow.
Guidance when you need it. Independent recall when you’re ready. Clear evidence of what to practise next.
Pick up where you stopped
Resume lab checkpoints, inspect your session history and transfer learning data with a manual backup.
Practise across your day
Short phone sessions, a larger iPad workspace and a Mac app with room for reference and keyboard input.

- This update included for existing owners
One-time in-app purchase. No subscription. Restore through Apple using the purchasing Apple Account.
Version 5.3 is being finalised for release. The App Store still offers the previous version. Mac has a separate review. Purchases retain the included-update promise.
Is this a real terminal?
No. Drills check command answers, and practical labs simulate a declared subset of machine state. Neither the app nor this website runs commands on your device’s operating system.
Do existing owners need to pay again?
No. The existing one-time Full Access purchase includes all tracks and future content updates, including this expansion. The App Store shows your local price before purchase.
Can I keep the familiar experience?
Yes. Classic remains the default. Adventure is optional in Settings, and both modes share progress, XP, content and purchases.
Is it an official RHCSA product?
No. It is an independent practice companion targeting RHEL 10. Practical content is labelled as awaiting independent technical review. Completion does not predict an exam result.
Can I study without an internet connection?
Yes. App learning content is bundled, with progress and checkpoints stored locally. Apple’s purchase and restoration services may need a connection.
When can I get version 5.3?
Version 5.3 is being finalised for release. This page previews the update; the App Store still offers the previous version. Mac availability will follow its separate review.
