The Exam
The AP test for this course consists of two sections. Section I, administered over a period of 1 hour 20 minutes, is comprised of 100 multiple-choice questions. Section II, which lasts 1 hour and 30 minutes, consists of 4 essay prompts to be answered comprehensively by the student. A mandated 10 minute reading period is held prior to beginning to write the four essays.
