The AP Statistics Exam consists of two sections: Multiple Choice and Free Response.  The exam is 3 hours long - 90 minutes per section.

Section I: MC Questions

90 minutes - 50 percent of exam score

SCORING:

40 Multiple Choice Questions

1 point for each correct answer

0 points for each question left blank

-1/4 point for each incorrect answer

Section II Free-Response Questions

90 minutes - 50 percent of exam score

Questions are designed to test your statistical reasoning and your communication skills.

SCORING:

Five open-ended problems; each counts 15 percent of free-response score. {~13 minutes per problem}

One investigative task @ 25 minutes; counts 25 percent of free-response score.

Each free-response question is scored on a 0 to 4 scale. General descriptors for each of the scores are:

4 = Complete Response {NO statistical errors and clear communication}

3 = Substantial Response {Minor statistical error/omission or fuzzy communication}

2 = Developing Response {Important statistical error/omission or lousy communication}

1 = Minimal Response {A "glimmer" of statistical knowledge related to the problem}

0 = Inadequate Response {Statistically dangerous to himself and others}

Your work is graded holistically, meaning that your entire response to a problem is considered before a score is assigned.
