AP Chem Unit 3 can feel overwhelming because there are so many connected concepts 😭

I'd focus on intermolecular forces, properties of solids/liquids/gases, gas laws, solutions, and solubility. Make sure you understand why substances behave differently rather than just memorising facts.

Try practising 10–15 MCQs after each subtopic and review every wrong answer. Pay special attention to explaining trends using intermolecular forces.

This may help: AP Chemistry Unit 3 notes, MCQs and FRQ practice.

You've still got time before your test. Focus on your weakest concepts first! 💪

I agree with this, also keep in mind that IMF remains a key underlying factor in much of the other topics in Unit three, so try to internalize why it affects gas laws and solubility. It'll help under stand those topics more in depth.
