🚀 You're jumping ahead. This builds on Time Value of Money — but play it now and you'll still earn full XP. If it feels steep, those make a gentler on-ramp.

A short lesson, then a quiz. ❤️×3 — a wrong answer costs a heart; finish with at least one left and the level is yours. Lose all three and you'll have to try again. Replay any time — XP and cleared levels are never lost.
