What You'll Learn

The exam is 8 hours long
The PE exam is an 8-hour-long test that is considered extremely difficult. It is designed for engineers with a minimum of four years of post-college work experience in their chosen engineering discipline. The exam covers a broad range of engineering topics, and the difficulty level varies by discipline. Engineers who take the exam often highlight its challenging nature due to the extensive preparation required and the mental endurance needed on exam day. The exam is no longer an open book, and there is a new test format that candidates are still adjusting to. This change means that engineers need to be very familiar with the reference handbook and other allowed materials as they cannot rely on their own notes and books during the exam.
The PE exam is a demanding test, but with a strategic approach, you can boost your chances of success. One engineer advised: "Don't dwell and move on. If you can't figure it out in the first 2-5 minutes, move on and come back to it." This underscores the importance of time management and the ability to stay calm under pressure. Extensive preparation is required, with engineers often spending months preparing and tackling numerous practice problems.
The exam includes 85 questions and is offered in either a pencil-and-paper format or as a computer-based test. The PE Power exam is now conducted in the latter format, and all exams are in the process of being shifted to computer-based. The exam fee is $400, payable directly to NCEES. Some licensing boards may require a separate application and fee as part of the approval process.
The pass rate for the PE exam varies, with first-time takers' scores ranging from 49% to 82%. The average passing score is approximately 59 correct answers out of 80. Most candidates claim that the PE Exam is the most difficult exam they have taken in their lives. It takes a significant amount of time, money, setbacks, and determination to pass. However, it is not impossible, and with the right mindset, resources, and motivation, you can succeed.

The exam is either in pencil-and-paper format or computer-based, and it is not an open-book exam.
The PE Electrical and Computer exam includes multiple-choice questions and alternative item types (AITs). It covers topics such as synchronous motors, synchronous generators, induction machines, transformers, motors, conductor sizing, overcurrent protection sizing, grounding, and bonding. The exam is demanding, and many candidates claim it is the most difficult exam they have ever taken.
Preparation for the exam can be extensive, with some candidates reporting studying for up to 8 months. Practice exams are widely recommended, and some sources suggest that the NCEES practice exams are particularly useful. However, it is important to be aware that some practice exams may contain errors or typos.
While the PE exam is undoubtedly challenging, it is not impossible to pass. With the right mindset, resources, and motivation, candidates can successfully pass the exam.

Requires extensive preparation
The PE exam is an extensive 8-hour test that demands a lot of preparation and covers a broad range of engineering topics. The exam is designed for engineers with a minimum of four years of post-college work experience in their chosen engineering discipline. It is regarded as a challenging exam, with an extensive amount of content to revise and a demanding test format.
Extensive preparation is required for the PE exam, and engineers often spend months preparing, tackling numerous practice problems, and covering a vast array of topics. The exam is not simply a test of knowledge but also of mental endurance, with the stress of the exam day and time constraints contributing to the challenge. The exam is no longer an open-book test, and this change in format requires a different approach to preparation and test-taking strategy. Engineers need to be familiar with the reference handbook and other allowed materials, as they cannot rely on personal notes and reference books during the exam.
To prepare for the exam, it is recommended to start early and follow a structured study plan. This includes regular practice with problems similar to those on the exam, as well as familiarity with the reference handbook and other allowed reference materials. Practice exams are a useful tool, with some sources recommending the National Council of Examiners for Engineering and Surveying (NCEES) practice exams, as well as those from reputable exam prep companies.
Some engineers have reported spending 7-8 months preparing for the exam, taking a more relaxed approach of 10-15 hours of study per week. Others have taken a more intensive approach, with one engineer reporting that they spent hundreds of hours practising, in addition to the considerable amount of money, setbacks, and determination required to pass.
The PE exam is a difficult test, and it is important to be aware of the extensive preparation required. However, with the right resources, mindset, and motivation, it is possible to be successful, and passing the exam is a huge accomplishment.

Mental endurance is key
The PE exam is an intense test of mental endurance. It is an 8-hour exam, and candidates often report feeling mentally exhausted by the end of it. The exam covers a broad range of engineering topics, and the difficulty level varies by discipline. The pass rate for first-time takers can be as low as 49%.
To prepare for the exam, engineers often spend months tackling numerous practice problems and covering a vast array of topics. This extensive preparation can lead to a build-up of pressure, which can be overwhelming on the day of the exam. It is important to remember that it is okay to guess and move on if you don't know the answer to a question. Practice exams can help with this, as they can make you more comfortable with the idea of not knowing all the answers.
The PE exam is no longer an open-book exam, which means that engineers need to be very familiar with the reference handbook and other allowed materials. This change in format can make the exam feel more difficult, as it requires a different approach to preparation and test-taking strategy. Effective exam preparation is key to success. This includes adequate study time, regular practice with similar problems, and familiarity with the reference handbook and other allowed materials.
It is also important to be wary of scare tactics and people who talk up the difficulty of the exam. While the PE exam is challenging, it is not impossible to pass. With the right mindset, resources, and motivation, you can successfully pass the exam.
