Must, Have to, Need to, and Don't Have to

When something is absolutely required, do you say "You must wear a uniform" or "You have to wear a uniform"? Both are correct — but what about when something is not necessary? Saying "You don't have to wake up early" means it's your choice, while "You mustn't wake up early" means it's forbidden. Mixing these up can completely change your meaning!

This challenge tests your ability to choose the right modal of necessity across real-life scenarios: school rules (uniforms, student IDs, arrival times), doctor's instructions (taking medicine, dietary advice), travel requirements (passports, check-in procedures, packing checklists), workplace dress codes, flatmate chores (bills, bins, bathroom cleaning), and gym membership rules. You'll practise distinguishing between must and have to for obligation, need to for necessity, and don't have to for things that are optional — not forbidden.

Work through 15 questions in four formats — single-choice, multi-choice, drop-down, and drag-and-drop — so you'll identify correct usage, spot common errors, and complete conversations in context.
