In this AP Precalculus review, we work through 20 of the most commonly missed question types on the AP PC exam — with a focus on the reasoning behind each answer, not just the steps. If you've been scoring close but not where you want to be, these are the gaps worth closing.
Topics covered:
- Zeros of transformed trigonometric functions
- Comparing logarithmic and linear models with a calculator
- Interpreting increasing/decreasing behavior from rate functions
- Finding when a quantity is maximized using sign changes in its rate
- Exponential regression and calculator-based prediction
- Sinusoidal models from circular motion
- Unit circle coordinates with negative angles
- Horizontal shifts of sine functions
- Horizontal dilations and translations using function notation
- Average rate of change from a table
- Least rate of change from tangent slope
- Decreasing and concave up behavior from tables
- Exponential decay — and why equal drops take longer over time
- Function composition with real-world units
- Holes in rational functions
- Rational inequality sign charts and multiplicity
- Logarithmic equations with domain restrictions
- Residual plots: overestimates, underestimates, and error size
- Polar average rate of change and linear approximation
- Polar motion toward the origin
This isn't a full-course review — it's a targeted look at the specific question types that trip up even well-prepared students. Watch it before your exam and go in knowing exactly where the traps are.
