Materials included in this Released Exam may not reflect the current AP Course Description and exam in this subject, and teachers are advised to take this into account as they use these materials to support their instruction of students. Finally, there is an entire chapter of statistical data about the exam and exam performance for that year, and advice on interpreting AP® grades. In addition to providing the multiple-choice questions and answers, the publication describes the process of scoring the free-response questions and includes examples of students' actual responses, the scoring standards, and commentary that explains why the responses received the scores they did. Approximately every four years, on a staggered schedule, the AP® Program releases a complete copy of each exam.
