How to Score Higher on AP Calculus AB
Multiple Choice
- Master derivatives and integrals of all common functions
- Know the Fundamental Theorem of Calculus inside and out
- Practice problems without a calculator - Part A is the majority of MCQ
- Review limits, L'Hôpital's Rule, and continuity definitions
Calculator FRQs
- Use your calculator to graph, find intersections, and evaluate integrals
- Always show the mathematical setup even when using calculator for computation
- Round final answers to 3 decimal places unless told otherwise
- Know how to store and recall values efficiently on your calculator
No-Calculator FRQs
- Show every step of your work - partial credit depends on visible reasoning
- Justify answers using theorems by name (Mean Value Theorem, IVT, etc.)
- Practice computing integrals and derivatives by hand until automatic
- For area/volume problems, always draw and label your setup
Reading tips helps. Writing a timed response helps more.
