AP Chemistry study guide
AP Chemistry rewards you for explaining why, not just calculating what. Most lost points come from a missing particle-level justification or a dropped unit, so practise naming the interaction, the equation, and the unit every time.

FAQ
How long is the AP Chemistry exam?
3 hours and 15 minutes: 90 minutes of multiple choice and 105 minutes of free response.
How many FRQs are on AP Chemistry?
Seven: three long questions and four short questions.
Where do most students lose FRQ points?
Justifications. The rubric wants the specific particle-level reason, such as the intermolecular force or the shift in equilibrium, not a general statement.
