State your direct answer (e.g., "The boiling point of NH3cap N cap H sub 3 is higher.")

While the curriculum covers nine units, these three areas usually carry the most weight and cause the most stress:

Expect to draw or interpret "dots in a box." Practice representing physical vs. chemical changes using circles to ensure you aren't losing atoms (Conservation of Mass). 3. Math Without a Calculator The Multiple Choice section is no-calculator . Estimation is your best friend: If you see , treat it as Cracking the AP Chemistry Exam

Often considered the hardest unit. Master buffers and titration curves . If you can identify the "half-equivalence point" on a graph, you can find the pKap cap K sub a instantly. 2. The "AP Style" Mental Shift The College Board loves to ask "Why?" rather than "What?"

When answering long-form questions, follow this template to ensure you get full points: State your direct answer (e

Never just say a molecule is "more stable." Instead, say it has "stronger Coulombic attractions" or "more polarizable electron clouds."

Usually, only one point on the entire exam is dedicated specifically to sig figs—don't let them paralyze you, but keep them in mind for the FRQs. Math Without a Calculator The Multiple Choice section

Here is a streamlined guide to help you dominate the 60 multiple-choice questions and 7 free-response questions (FRQs). 1. The "Big Three" Heavy Hitters
