Welcome! This tutor lets you practice one chapter at a time. Pick a chapter below and answer 20 multiple-choice questions. The questions start easy and get harder each time you answer correctly; if you miss one, the next question stays at the same level so you can master it before moving on. Many questions include a diagram to reason from. Every question is freshly generated — the numbers, names, goods, and brands change on each run — so no two attempts, and no two students, see quite the same quiz. There is no login and nothing is saved, so practice as often as you like.
A dress rehearsal for the real thing: questions from every chapter, interleaved, with no feedback until the end and a countdown clock. When time runs out the exam submits itself. No hints, no story mode.
Short simulations you actually play. Move the sliders, watch the market respond, then read what the theory says about it. Nothing here is graded and nothing is saved.
