The multiple choice section of the exam is composed of 40 questions of different difficulty levels. Do not spend too much time on any particular problem,
because you only have 90 minutes to answer the 40 questions.

The free response section of the AP Statistics exam is composed of 6 problems, usually broken up in smaller parts. Most problems start with a description
of a specific set-up, followed by questions labeled a), b), c), d) and e).
