About the AP Precalculus diagnostic

Build a strong foundation in functions, trigonometry, vectors, matrices, and complex numbers to prepare for calculus.

This diagnostic is a starting point rather than a practice exam: it samples the whole syllabus so you can see which units you already know and which ones need the work, before you spend study time guessing.

Units on this diagnostic

Questions are drawn from all 12 units of AP Precalculus, covering 61 topics in total.

How to use your results

The score report is broken down by unit. Start with the unit you scored lowest on rather than the one you enjoy most, work through its lessons and exit quiz, then come back and take the diagnostic again to confirm the gain is real.

Common questions

What does the AP Precalculus diagnostic cover?
It draws on all 12 units of AP Precalculus: Function Fundamentals, Polynomial and Rational Functions, Polynomial & Rational Functions, Exponential and Logarithmic Functions, Exponential & Logarithmic Functions, Trigonometric Functions, Function Analysis, Trigonometric Functions, Functions Involving Parameters, Vectors, and Matrices, Polar, Vectors & Matrices, Sequences, Series & Conics, Introduction to Calculus Concepts.
Is the AP Precalculus diagnostic free?
Yes. The diagnostic and your results are free to use.
What happens after I finish?
Your results break the score down by unit, so you can see which ones cost you the most points, and you can start a study plan built from that result.
Can I take it more than once?
Yes. Each attempt draws from a different form, so a retake is new questions rather than the ones you just saw.
