Once per year, at the May administration.

What is the best way to study for the AP Statistics?

Study the official blueprint, not random material: the exam is weighted by domain (Exploring One-Variable Data 15–23%, Exploring Two-Variable Data 5–7%, Collecting Data 12–15%, Probability, Random Variables, and Probability Distributions 10–20%, Sampling Distributions 7–12%, Inference for Categorical Data: Proportions 12–15%, Inference for Quantitative Data: Means 10–18%, Inference for Categorical Data: Chi-Square 2–5%, Inference for Quantitative Data: Slopes 2–5%). Spaced-repetition flashcards built domain-by-domain against that blueprint are the most time-efficient way to cover everything the exam tests.
