PFE - Multiple Choice Section
Multiple Choice Section
The multiple choice section is the first section of the exam that will be taken. This section is comprised of 60 questions and timed at 90 minutes. As general advice it should be noted that this only allows 90 seconds per question; therefore, students should not linger on a single question for more than this time to give them a better opportunity to answer all of the questions in the appropriate amount of time. As a reminder, calculators are now allowed on the multiple choice portion of the test. Also, be sure to ask your instructor to release previously published multiple choice exams as these are some of the best resources to assist you while studying for this exam.
