All nine units, one continuous scroll — 100 original multiple-choice questions sequenced from foundational to exam-level difficulty, mirroring official AP Statistics Section I weighting and pacing.
Directions. Questions are arranged in five ascending difficulty bands, with units interleaved throughout each band so concepts stay mixed rather than blocked — the same way they appear on the actual exam.
Scoring. Select your answer for each question. Feedback, the verified correct answer, and a short explanation appear immediately below the question — work through it before moving to the next one.
Hints. Each question includes an optional, collapsed hint. Try the question first; open the hint only if you're stuck.
Printing. Use the print button for an ink-efficient version with a full answer key on the final page — ideal for offline, closed-book practice.
