The Principles and Practice of Engineering Exam (PE) is a multiple-choice exam that assesses a candidate’s knowledge of process engineering. The exam covers topics such as process safety, mass and heat transfer, and chemical reaction engineering.

The PE exam is a grueling 8-hour test that covers a wide range of topics in engineering. Therefore, being well-prepared before taking the exam is important, as exam-specific information can be very challenging.

There are a few different ways to study for the PE exam, and the best approach depends on your learning style and the amount of time you have to prepare.


How to Study for PE Exam

You’re ready to start preparing for the PE exam. Great! One of the first things you’ll do is secure study materials or enroll in a PE prep course.

With so many options to choose from, this can be difficult to do!

To assist you in finding the most suitable PE exam reference materials, we’ve provided some options below for you to consider. Then, with the right approach, you will be ready to take the actual exam on exam day.

Review Course

The best way to get prepared is to take a PE review course. Universities or private companies typically offer review courses and provide an overview of all the topics covered on the exam.

PE study materials

The best PE review courses will include online and print resources, live or video lectures, practice problems, and full-length practice exams—all of which are essential for success on the PE exam.

These PE courses from the School of PE and PPI2Pass can take anywhere from several days to several weeks to get through and usually come with a personalized study plan to keep you on track.

They can be expensive but are a good option for those who want comprehensive preparation using the best resources.

Many offer money-back guarantees as well, so there’s less risk.

Self-Study

If you cannot afford a review course or if you prefer to study independently, there are a number of self-study resources available to help you prepare for the exam. Many universities offer free or low-cost online courses that cover the topics tested on the PE exam.

In addition, there are several commercial study aids, such as textbooks, workbooks, and online practice exams, that can be purchased to supplement your self-study.

Because these companies have taken the time to tailor their practice exam materials to the test, they’re usually a good way to gain experience solving realistic practice test problems.

While self-study may require more discipline than taking a review course, it is typically a more affordable form of exam prep.

No matter which method you choose, it’s important to start studying early. You’ll also want to create a study schedule that you can stick to. Dedicate a certain amount of time each day or week to studying, and make sure you stick to that schedule.

Practice Tests

One of the most important things you can do when studying for the PE exam is to take practice exams. A practice exam will not only help you get familiar with the format of the exam, but it will also give you an idea of what topics you need to focus on.

When you’re taking practice exams, it’s important to time yourself, as it’s a great way to get an idea of how long each section will take you and plan accordingly on the day of the exam.

Most PE review courses come with mock exams, but you can also purchase them individually.

The exams are computer-based and include all the question types you’ll see on test day, such as multiple-choice, fill-in-the-blank, and drag-and-drop.
