Repair Heroes

• Pick any mission — any order. Read it, then do the Quick check: say your answer out loud before you reveal it.
• Earn a star by finishing that mission's short round. Ten-ish stars = Study Master.
• Laugh + move. The jokes and brain-breaks aren't extra — they're how your brain glues the ideas in.

Why this works (real studies): quizzing yourself beats re-reading, short-and-often beats long-and-once, and a joke that's about the idea helps you remember the idea. This is a study structure, not a promise about grades.
