Skill Mode
Learn one capability at a time. Every assignment ends with a result you can check against the data, and has a worked solution you can open once you've tried. As you move up, assignments give you less procedure and more problem: A guided steps, B an objective, C a problem to diagnose, D an ambiguous situation to decide on.
