AP Calc AB Exam Tips

โฑ๏ธ
Know the Format
Section I: 45 MC no calculator + 15 MC with calculator. Section II: 2 FRQ no calc + 4 FRQ with calc. Total 3 hr 15 min.
๐Ÿ“
FTC is Everything
The Fundamental Theorem of Calculus connects derivatives and integrals โ€” it shows up in almost every FRQ. Master both parts cold.
๐Ÿ–Š๏ธ
Show Your Work
FRQ graders award process points. A correct final answer with no work shown can score 0. Write setup equations clearly.
๐Ÿ”‘
High-Weight Units First
Units 5 and 6 together make up ~35% of the exam. Lock down analytical applications and integration before anything else.
๐Ÿ“Š
Practice Slope Fields
Slope fields and separable DEs (Unit 7) are nearly guaranteed on the FRQ section โ€” don't skip them.
๐Ÿงฎ
Calculator Sections
On calculator FRQs, use numerical integration and derivatives freely. Store intermediate values โ€” don't re-key them.
