Is the science quiz for kids free?

Yes. Every quiz on Exampractice is completely free — no payment, no subscription and no adverts. No account is needed to play; sign in whenever you like and your scores, streak, level and friends are kept across devices.

How many questions are there and how long does it take?

A set is 10 questions with 15 seconds each, so a full round takes under three minutes. Questions run from easy to hard and no two sets are the same.

How is the quiz scored?

Easy questions are worth 100 points, medium 200, hard 400 and extra hard 800. Consecutive correct answers add a streak bonus of up to 15%, and in Quick Play a fast answer adds up to 20% more.

Is it suitable for children?

Yes — the Kids Science questions are written for younger players, and Kids Zone groups only ever use Starter-level questions. A parent’s account keeps the scores.

Do the questions get harder?

Yes. Everyone starts on Starter sets and unlocks Regular, Advanced and Expert mixes by finishing sets accurately — extra-hard questions only appear from Advanced onwards.
