FE Exam Failure Analysis: Unmasking the Most Common Reasons Students Don't Pass

The Fundamentals of Engineering (FE) exam is notorious for its difficulty, with an average year-round passing rate of about 60% as of July 2023. Obtaining an Engineering in Training (EIT) certification proves to be a major challenge and roadblock for many students and engineers, even having graduated from an accredited program and university. The reasons behind the nearly half fail rate for FE examinees are often misunderstood or oversimplified; in this blog, we will take a deeper look at the true underlying causes and provide advice to help future test takers succeed.
FE Exam Failure Analysis
Numerous Factors at Play
At first glance, it seems obvious that inadequate technical knowledge or preparation is the root cause for the strict passing rate, however, rarely is there ever a sole or even primary reason for failure. Not every engineer has the same background, nor the same circumstances in their lives, and it would be ignorant to paint with a broad brush as to why every examinee who missed the mark failed. A multitude of factors can contribute to not succeeding in their efforts: time management, resource allocation, improper preparation, and overstressing can all affect an examinee’s success.
Underestimating the Exam
Often, first-time takers of the FE underestimate what actually taking the exam is like, as a result, they are ill-prepared for what is in store for them. The FE covers a broad range of fundamentals from the first two years of an engineer’s schooling. For most students, who have completed their studies in earnest, they possess the knowledge of engineering fundamentals required to pass; granted, if proper review of technical weaknesses is undertaken. Attempting to pass such a critical examination just by memorizing equations and study guide answers without any effort to grasp the concepts truly is certainly misguided. This can quickly be remedied, to do so, diligently study any encountered problem areas and thoroughly practice analytical problem-solving techniques, with that, success is far closer to grasping than before.
Pressure of Standardized Testing
Another enormous obstacle for many examinees of all experience levels is the psychological game and pressure of high-stakes standardized tests. Because the FE exam is composed of 110 difficult multiple-choice questions, test takers require strong mental stamina to maintain focus and complete the exam within the allotted 6 grueling hours. Sitting for 6 hours straight induces mental fatigue and strains concentration, all exasperating probably already high-test anxiety. Self-doubt and negative thoughts may intrude, and can severely impact reasoning skills needed for complex analytical questions. The best practice to overcome the overwhelming feeling of the clock is to build resilience through simulated practice exams; and set aside a day to become immersed in the exam environment. Preparation under as close to the real deal as possible will reduce stress and boost confidence in one’s preparation, which are critically important for success.
Time Management Concerns
Poor time management is an incredibly common pitfall many engineers make during the exam, and getting derailed by difficult or unfamiliar problems. To complete all 110 questions within the time limit, the FE requires test takers to solve each problem at a brisk and steady pace, averaging just 3 minutes per question. Lingering too long on any single problem consumes valuable time that should be spent on easier questions. Test takers should restrain the urge to perfectly solve everything, and instead skip and mark problems causing delay. Here is where practice exams and study guides help in time allocation; identify areas that require more attention and which topics can be tackled quickly. Developing quick estimating skills and intuition for when to cut losses and move on will greatly improve efficiency. Pacing and time management under pressure must be practiced.
Problem-Solving Problems
Strong fundamental problem-solving skills go hand in hand with time management; the FE tests a wide variety of engineering concepts and analytical frameworks, and test takers are expected to not only solve these problems but also carry this knowledge into the workforce. Yet, there are many students and engineers who rely too heavily on memorized procedures versus true first-principles understanding. For complex problems, knowing the underlying physical relationships, principles, and functional dependencies is far more valuable than following rote steps. Test takers need to sharpen skills for breaking down and simplifying problems using basic conceptual knowledge, in order to not become over-reliant on memorization, it is recommended to take multiple practice exams to solidify the concepts on the FE. Learning to qualitatively estimate solutions and check answers also avoids getting stuck in calculation steps.
Testing Strategies
Beyond academic and technical skills, general test-taking strategies make a big impact. Error avoidance should be prioritized over speed while still maintaining pace. Double-checking units, signs, and calculations will minimize costly mistakes. Also, FE problems are designed with tricky nuances, so reading questions and answers very carefully is essential. Actively annotating and taking notes directly on the test booklet can help improve focus. And for computer-based exams, flagging questions to come back to saves time. Practicing these test-taking habits will pay off tremendously.
Feeling Performance Stress
Lastly, treating the FE as a one-time high-stakes event induces greater pressure than necessary. Failing once or even twice is normal and should be viewed as part of the multi-step learning process. Having an incremental growth mindset is far more productive than an all-or-nothing mentality. Test takers who view preparation as a long-term endeavor spanning months will experience less stress while systematically building knowledge and skills. With steady improvement over time and perseverance, passing the FE is an achievable milestone, not an insurmountable barrier.
Conclusion
A mix of technical and psychological factors underpin the common struggles to pass this challenging exam. While a minimum level of academic preparation is mandatory, developing persistence, problem-solving efficiency, time management, and stress management may be just as important. By understanding the true root causes behind FE exam difficulties, future test takers can shift their approach and set themselves up for success. The FE may carry the notoriety of being an insurmountable challenge, but that is further from the truth for all engineers on the journey to becoming a licensed professional engineer. With the right strategic approach, passing is within reach.

Zoox Robotaxis: The Future of Urban Transportation? (Benefits, Safety & Availability)

Zoox Robotaxis
Self-driving cars have long been a staple of science fiction, but Zoox - a California-based startup - aims to make autonomous urban transportation a reality very soon. Zoox has designed a fully electric, driverless vehicle from the ground up to safely shuttle passengers to their destinations. This robotaxi offers a preview of how we may one day hail a driverless taxi/bus.
Zoox Vehicle Design
Zoox Vehicle Design
Zoox’s vehicle has been designed to have a sleek futuristic look while seating four passengers. Zoox vehicles are able to drive forward and backward with equal capabilities. This is enabled by its four-wheel steering and two sets of identical sensor configurations on both the front and back. With the implementation of AI choreography, Zoox vehicles deftly maneuver in tight spaces by sliding sideways into parking spots, removing the need for three-point turns, backing up, or tricky maneuvers for human drivers. The interior feels roomy and comfortable, with seats facing each other to facilitate conversation. There is no steering wheel, brake pedals, or driver controls inside - it is made to be fully autonomous (Zoox, n.d.).
Autonomous Driving Software
Autonomous Driving Software
The company has innovated both its vehicle design and the self-driving software powering it: what the Zoox engineers have built is what they have described as an “AI co-pilot” capable of navigating busy and unpredictable urban environments. Zoox's artificial intelligence software. processes the torrent of sensor data. Their programs use deep neural networks - inspired by the human brain - to analyze sensor input and make driving decisions. The AI extracts key information like lanes, signs, lights, objects, and pedestrians. It predicts the behavior of other road users and plans safe, efficient routes and motions second-by-second. Zoox's AI leverages large datasets and simulations to train extensively before testing on public roads (Zoox, n.d.).
Zoox vehicles are studded with sensors to achieve 360-degree perception. This includes cameras, lidars, radars, and ultrasonic sensors. The camera system includes wide field-of-view and telephoto lenses to see objects both close-up and at a distance in high resolution. The lidars bounce lasers off surrounding objects to measure distance with precision day or night. Radars complement this by detecting objects and measuring velocity. Ultrasonic sensors fill in blind spots around the vehicle. Fusing all this sensory input enables sophisticated scene understanding (Zoox, n.d.).
Zoox has fleet coordination in which individual Zoox vehicles will coordinate with the larger fleet for optimal routing. A fleet manager AI will track all of the vehicles' locations and statuses. With that information, it can then assign and reroute vehicles to meet ride demands, avoid congestion, and keep the service running smoothly. All of this will rely on fast vehicle-to-vehicle and vehicle-to-cloud communication (Zoox, n.d.).
Envision Consumer Experience
For passengers, the experience aims to be seamless. You simply hail a Zoox robotaxi using their app, get in and fasten your seatbelt, and then input your destination. The vehicle handles the rest - expertly maneuvering streets, obeying traffic laws, avoiding obstacles, and smoothly dropping you off at your destination. Throughout the ride, you can relax and enjoy the journey without the stress of driving yourself.
Potential Societal Impacts
Zoox envisions a world where you do not own a car but simply hail a robotaxi whenever needed. This could allow cities to reclaim parking spaces for more green spaces, bike lanes, and wider sidewalks—and other uses that improve urban life. While you ride in a Zoox, you’re unlikely to get stuck in traffic. With real-time coordination, their fleet aims to optimize routes and keep everything moving efficiently.
The environmental benefits could also be immense. Zoox vehicles are all-electric with zero tailpipe emissions. Large self-driving fleets would drastically reduce the number of cars on the road. Even with electricity generation, experts estimate autonomous ride-hailing could cut greenhouse gas emissions from transportation by over 90%.
Safety
Safety
With any autonomous vehicle, safety remains paramount. Zoox is putting their vehicles through rigorous closed-course and public road testing. They are focused on building advanced safety cases, risk assessments, and driver monitoring tools to ensure their system performs at least twice as safely as human drivers before commercializing. Monitoring passengers with onboard cameras not only helps keep them safer but also encourages improved behavior.
In addition to the sensors and AI, Zoox vehicles have safety measures like emergency airbags and a rear-impact crumple zone. Their system architecture is designed for redundancy, with duplicate computers and power sources in case of failures. The vehicles are to undergo rigorous physical testing and crash simulations, ensuring that passengers will be protected from danger (Zoox, n.d.).
The Future with Zoox
The Future with Zoox
Zoox has achieved major autonomous driving testing milestones recently. After securing a driverless testing permit from California's Department of Motor Vehicles (DMV) in 2023, their purpose-built robotaxi completed a historic first voyage on public roads without any manual controls or safety drivers. This marked the first time a fully autonomous passenger vehicle designed specifically for ride-hailing navigated open public roads. Zoox also expanded to facilities in Las Vegas, Nevada, and gained approval from the Nevada DMV to test their self-driving robotaxis on public roads there as well. By gaining permits in California and Nevada, Zoox can further validate the autonomous capabilities of their ground-up robotaxi through rigorous real-world piloting. These advances indicate Zoox's progress toward deploying a commercial driverless ride-hailing service in the coming years (Zoox, n.d.).
Conclusion
When might you start seeing bright green and blue Zoox cruisers taxi through your neighborhood? According to them, they hope to launch commercial service in certain cities over the next few years; however, scaling up to widespread availability may require significant time. The technology still has limitations to overcome, regulations to navigate, and public trust to earn, but if this ambitious vision is delivered, then your commute may someday be as simple as hailing your own AI chauffeur.
Zoox provides an exciting glimpse into a possible future that prioritizes mobility efficiency, safety, accessibility, and sustainability over individually owned vehicles. In light of the progress that we have seen so far, this innovative design and well-incorporated artificial intelligence aims to revolutionize how cities move.

FE Exam Without an Engineering Background: Is It Possible? Here's the Truth

The Fundamentals of Engineering (FE) exam, also known as the Engineer in Training (EIT) exam, is the first step in becoming a licensed professional engineer in the United States. The exam is designed to test an examinee’s basic engineering knowledge, which is typically acquired through an undergraduate engineering degree. While that may be the case, there have been a few wondering “if it is possible to take and pass the FE exam without having the typical working engineering knowledge?”. The answer is maybe that not only would this endeavor be quite challenging, but the subject matter is not the only factor that decides whether or not someone could take the exam. Here's an overview of the FE exam and the feasibility of taking it without an engineering background.
FE Exam Without an Engineering Background
What is the FE Exam?
The FE exam is a 6-hour computer-based test administered year-round by the National Council of Examiners for Engineering and Surveying (NCEES). It covers core engineering subjects such as mathematics, statistics, chemistry, physics, engineering economics, ethics, and basic engineering principles within specific disciplines: Chemical Engineering, Civil Engineering, Electrical & Computer Engineering, Environmental Engineering, Industrial & Systems Engineering, Mechanical Engineering, and Other Disciplines.
As of 2024, the exam currently consists of 110 multiple-choice questions. The exact topics, however, vary slightly depending on the chosen engineering discipline; the specific subjects tested can be viewed on the NCEES website and through the exam specifications provided information.
Passing the FE exam demonstrates an understanding of basic engineering concepts and the specific discipline chosen, but it is also often the first step to acquiring an entry-level engineering position in certain industries. Obtaining an EIT certification is also required to move forward to taking the Principles and Practice of Engineering (PE) exam, which is necessary for professional engineering licensure.
Who Typically Takes the FE Exam?
Before taking the FE without a traditional background in engineering, let us go over who the exam was written for. As stated by the administrator of the exam, NCEES, the FE exam is recommended for recent engineering graduates and working engineers.
Current engineering students and recent graduates who have completed an EAC/ABET-accredited engineering program still likely have the material they learned in class fresh in their minds, making them great candidates to take the exam and pass.
The ABET (Accreditation Board for Engineering and Technology) is an ISO 9001-certified organization that accredits most engineering degree programs internationally. ABET-accredited programs would typically cover the fundamentals tested on the FE exam.
Working engineers may also take the FE exam, especially if their undergraduate degree is from a non-accredited program. The FE exam should be taken for those who are in an industry where professional licensure is required for promotions and contracting. In some states, it is required to pass the FE exam for licensure, even for experienced engineers with many years under their belt. The examinee must have the proper educational and experience credentials to register for the exam.

Is It Possible to Take the FE Exam Without an Engineering Degree?
The FE exam does not explicitly require an examinee to have an engineering degree before they are able to take it, and in some cases, engineering students are able to take it before receiving their degree. Ultimately, eligibility varies by state licensing boards, but most require a degree in engineering or engineering technology from an ABET-accredited program. Some states allow applicants to substitute education and work experience to demonstrate equivalent knowledge, and there are a few that allow anyone with a college degree in a STEM field to take it.
Without having the typical engineering educational background, is it possible to independently acquire the knowledge needed to pass the exam? Perhaps, with the right combination of self-study, practice, and determination. There is a plethora of study guides and preparation materials online, and the FE Reference Handbook provided as a study resource for the exam can supplement some fundamental knowledge gaps. Even without enrolling in engineering, topics like mathematics, physics, chemistry, and economics align with non-engineering curriculums. It is possible for an examinee to intensely self-study engineering principles not covered in their degree program, but obviously, this would require a significant amount of effort.
Steps to Prepare for the FE Exam Without an Engineering Degree
For the determined non-engineer wanting to tackle the FE exam, here are some steps to set yourself up for success:
  1. Ensure that your state licensing board allows you to take the FE without actively pursuing or already obtaining an engineering degree from an accredited program.
  2. Choose an engineering discipline exam that best aligns with your background or interests. Mechanical, electrical, civil, and chemical are common options for non-engineers.
  3. Obtain the NCEES FE Reference Handbook and examine the topics covered in the exam specifications for your chosen discipline. Identify knowledge gaps.
  4. Study FE exam prep books and materials. Many focus on the fundamentals tested and provide practice problems with solutions. Work through them meticulously.
  5. Master mathematics completely. Math is a significant component of the FE exam, so ensure algebra, trigonometry, calculus, probability, and statistics are locked down.
  6. Enroll in online courses to fill discipline-specific knowledge gaps. Many platforms, like School of PE, offer FE exam reviews or engineering fundamental courses to supplement self-study.
  7. Solve hundreds of practice exam questions. FE exam prep books and online resources provide realistic multiple-choice questions. Practice makes perfect.
  8. Don't neglect studying the general engineering principles that span disciplines, like engineering economics, ethics, and quality control.
  9. Maintain confidence in yourself. With diligence and commitment, passing the FE exam without an engineering degree IS possible. Be mentally resilient.
Conclusion
The intensive preparation required gives non-engineers a shot at passing the FE exam, though the path is undoubtedly tougher. Obtaining an engineering education and gaining practical experience before testing will set any examinee up for an easier journey. While the FE exam is passable without working engineering knowledge, hands-on learning facilitates deeper mastery of the concepts and skills tested. For non-engineers, passionately immersing oneself in a self-driven engineering education may be the ticket to success. With determination and hard work, the FE exam can be conquered by those willing to put in the effort.
Whether you are a current engineering student or someone who graduated from their engineering program many years ago, School of PE can help you prepare with confidence for your FE exam. Learn more about our courses today or register now!
