Why this works Arena Labs Loop
For sequencing, reasoning, and command meaning inside a real system context.
Learn in modules, rehearse in Arena, deepen in Labs, then return to the next lesson.
Do not over-practice the wrong mode
If the concept is still fuzzy, go back to the lesson. If the concept is clear but recall is weak, drill. If the command is known but the workflow is shaky, use a lab.
