Item Sets

An Item Set is a handful of questions built around one scenario, answered in a fixed order rather than shuffled — each step can build on what an earlier one revealed, the way a real problem unfolds rather than a list of unrelated facts.

Item Sets play like the regular Practice Quiz: hints, hearts, and XP all work the same way. The difference is order — you can't skip ahead or answer steps out of sequence.

Not every chapter has one yet. When a chapter does, you'll see an Item Sets card on the chapter page listing each one and how many steps it has.
