The AP Chemistry exam format will be changing for the May, 2014 exam administration. The AP Chemistry exam is a three hour and fifteen minute timed exam, consisting of two sections. Each section is weighted equally--i.e., each portion will determine 50% of the overall grade.
Section 1--Multiple Choice
Students have 90 minutes to complete 60 multiple choice questions, which cover the entire curriculum. Each multiple choice question will have 4 possible answers (down from 5 in previous exams), and there will be no "guessing penalty" for incorrect answers--the student score depends only on the number of questions answered correctly in this section. New for this exam are "question sets" relating to a common data set or information. Students are not allowed to use calculators during the multiple choice portion of the exam, but students will have access to a periodic table and an equations reference sheet.
Section 2--Free Response
Starting with the May 2015 exam, students will have 105 minutes to complete 7 open response items. Experimental design and data analysis, as well as particle-level representations and computation problem solving, will be distributed throughout this portion of the exam.
