Dr. Green: "Welcome, chemist! This quest reviews everything from Unit 3: how to classify matter, what's inside an atom, why atoms bond, how gases behave, and all the mole conversions. Some labs are multiple choice and some ask you to type a number. For typed answers use scientific notation like 2.2 × 105 (type it as 2.2e5) and mind your significant figures. Clear a lab with few mistakes to earn stars and unlock the next one."
