FEATURED TESTIMONIAL- Dr. Tom’s Recipe for Success!

“My biggest concern was where to begin and how to organize all of the information, and relearning the topics in time. Dr. Tom guided us with a cookbook method of organizing the info and provided an Exam Day Companion that concisely summarized most of the reference info in one notebook. He defined for us the number of hours needed for prep. I felt that Dr. Tom saw everything from the test takers point of view. He was always very respectful, dedicated and personable. You will not find anyone else more committed. I would most definitely recommend Dr. Tom's Review to others preparing for the ME PE Exam. It was very helpful, but Dr. Tom can't do it all. If a student wants to pass on the first try, they need to put in the 300 hrs of quality prep time that Dr. Tom recommends.”

CBT Brings New Types of Questions


In this installment of my posts on the scheduled transition to Computer-Based Testing (CBT) format for the Mechanical PE Exams in 2020 and the Civil PE Exams in 2023 (https://ncees.org/exams/cbt/), we look at the new question types that will be introduced with the new CBT exam format. 

The new CBT exams will not only have the traditional multiple-choice questions but four additional question types. They are referred to by the NCEES as AITs, Alternative Item Types. The four new question types include:
Multiple correct options – allows multiple choices to be correct and can have more than the usual four possible answers
Point and click –  click on part of a graphic to answer
Drag and drop – click on and drag items to match, sort, rank, or label
Fill in the blank - space provided to type a response to the question. 
While these changes allow for a whole host of new type problems, not being familiar with how these are to work could be troublesome. For example, will spelling be a problem with fill-in-the-blank questions?  Spelling was never my strong suit. Will 23,000 and 23000 both be acceptable?

Currently, the Pencil-and-Paper PE Exams are all multiple choice with four possible answers – a very familiar format that we have come to expect in these type exams, and one that presents no unknown factors to provoke additional anxiety. Just another reason to take and pass the PE Exam now before the Pencil-and-Paper exam is no longer an option.

Hurricanes and Transportation Infrastructure

Transportation networks are particularly critical during times of emergencies. With the impending arrival of Hurricane Florence, aircraft owners are moving their aircraft to safer locations, interstate lanes have been reversed to take drivers inland away from the predicted locations of impact, and other modes are used to relocate people and goods. These emergencies emphasize the importance of our civil engineering infrastructure and their continued maintenance and operation to serve our society. - Daniel Findley, DTC Civil Transportation Instructor

From all of the Dr. Tom team, for those of you in the path of the Hurricane, please stay safe!

“If you don’t read my entire testimonial – here is the 'bottom line upfront:' Look no further! Like many other folks, I had previously taken the Mechanical PE exam without a great deal of structure.  In fact, after two unsuccessful attempts in the mid 1990’s – I placed professional registration on hold – uncertain if I would ever try again. However, with life and work ever-changing, it became clear that professional registration would be a benefit. Needless to say – I passed the Mechanical Thermal/Fluids exam and a great deal of credit goes to Dr. Tom and the course.  If you work the program, watch the lectures, do the problems, participate in the weekly discussions, prepare the personalized resource notebooks, and use the participant forum…..you will pass the exam. This structure, organization, and commitment are why this program is so successful and I will be recommending this to my colleagues. Thank you Dr. Tom and your entire staff.”

Time Allotment – CBT Exam versus Pencil-and-Paper Exam


In this installment of my posts on the scheduled to transition to Computer-Based Testing (CBT) format for the Mechanical PE Exams in 2020 and the Civil PE Exams in 2023 (https://ncees.org/exams/cbt/), I want to take a closer look at how meeting the challenge of time management differs on the CBT PE Exam and the Pencil-and-Paper PE Exam. Time management is troublesome for all of us, especially on tests, and particularly on a test as important to one’s future as the PE Exam. So it’s worth taking a look at these differences. 

Let’s start with the current Pencil-and-Paper exams, which are 8 hours total divided into two 4-hour sessions with and an official 1-hour break in between. You have exactly 40 questions to answer in the first 4 hours and exactly 40 questions in the second 4 hours. There is a big clock on the wall and periodically the time remaining will be announced. Time is called after each of these sessions, and all work is to be stopped. Time management is handled by the NCEES representatives, leaving your mind free to concentrate on the exam. You certainly need to pace yourself and make sure not to get stuck on tricky problems, but one nice thing about this format is that there is no chance that you will take more time on the first 40 questions and then not have enough time for the second 40 questions.

Now let’s look at the CBT exam. It is not official, however, it can probably be assumed that the time allotment for the CBT versions of the Mechanical and Civil PE Exams will be the same as the current CBT Chemical PE Exam. The time you have remaining is shown on the screen and continues to count down as you work through the exam. The total time is 9 hours, broken down as follows:
  • 2 minutes to read and sign the Nondisclosure Agreement. If you don’t sign, it is over.
  • 8 minutes for an online tutorial on how to navigate the exam screen.
  • 8 hours for the exam.
  • 50 minutes for a lunch break, where you decide when to take the break. You will want to take this break after 4 hours where hopefully you have had a chance to answer half of the 80 questions. If you don’t take a break, you lose the 50 minutes; it does not add to your time. If you spend more than 50 minutes on your break, the exam time clock re-starts after the 50 minutes. At the end of 8 hours to the second, the exam is over.
With the CBT format, you must be vigilant in your time management, because you have to decide when you take the break and you have to make sure you allow enough time to get to all 80 questions. Another thing to worry about during the exam. 

The only way to avoid the extra pressure of time management associated with the CBT exam format is to take and pass the exam now. Once the last Pencil-and-Paper exam is administered in your discipline, you’ll be stuck with CBT.

FEATURED TESTIMONIAL - Take On the PE Exam with Confidence

“Dr. Tom's 20-Week course helped me learn everything I needed to pass the Mechanical: Thermal & Fluid Systems exam on the first try. He did a better job of explaining the material better than most of my professors. He was always very friendly and easy to understand. The best part about the 20-Week Review is that you develop a weekly schedule of what you need to work on. Material is not crammed into a 3 or 4 week review like some other PE courses. With the 20-Week Review, you gradually rebuild and strengthen what you learned in college so you can take on the PE exam with confidence. The Exam Day Companion is worth it's weight in gold! I have already recommended my coworker to the course and he will be starting it this spring, and I will encourage other ME's to take the course. It was also the cheapest course I was able to find. I just wish I could shake Dr. Tom's hand and tell him thank you for everything!

Nuisance Flooding Gets a New Definition

Nuisance flooding, or “sunny day flooding” has been in the news a lot lately. These types of floods can occur when the position of the sun and moon align such that the tide range is higher than normal. In general, these floods don’t cause major property damage or seriously threaten public safety. But nuisance floods can strain infrastructure like roadways and sewers, provide habitats for mosquitoes and bacteria, affect property values, and discourage tourism. In places where such floods happen all the time, the cumulative costs may add up to be equivalent to one big hurricane!

Most people “know nuisance flooding when they see it”, but there hasn’t been a consistent definition of when this occurs. To arrive at a clearer definition, Moftakhari et al. did a massive literature review on nuisance flooding. They looked at a range of different factors of nuisance flooding, including pedestrian safety, property damage, hydrology, and transportation impacts. On the basis of this research, the team came  up with the following definition: A nuisance flood is a layer of water between 3 and 10 centimeters high, traveling at a speed of less than 3 meters per second.  The new definition can help cities measure the cumulative impacts of nuisance floods and encourage flood-resilient construction. - Beth Sciaudone, DTC Civil Water Resources & Environmental Instructor

Allowable Items – CBT Exam versus Pencil-and-Paper Exam


In this installment of my posts on the scheduled transition to Computer-Based Testing (CBT) format for the Mechanical PE Exams in 2020 and the Civil PE Exams in 2023 (https://ncees.org/exams/cbt/), I want to take a closer look at the difference in what you’re allowed to take into the CBT PE Exam (which is virtually nothing) and what you can take into a Pencil-and-Paper PE Exam (which is almost anything useful within reason). 

The downloadable NCEES Examinee Guide contains information for the both the CBT and Pencil-and-Paper exams, including a list of what items you are allowed to have during the exam.

For the CBT exam, this list of allowed items is very limited.  The following items are allowed: official ID, one approved calculator without cover (spare must be in locker), a key to the locker, booklet and marker supplied by Pearson VUE, eyeglasses without the case, light sweater or jacket, and approved medications. You will be given a pad and a special pen to do all your calculations, which will stay in the exam facility when you have completed the exam. You may ask for additional pads or pens during the exam. That is it. Then there is the long list of items not allowed. Cell phones and computers, of course, fitness trackers, pagers, watches, wallets, purses, hats and other head coverings (unless religious in nature), bags, coats, books, notes, pens, pencils, erasers, food, and beverages. Please note that books and notes are included in the list of banned items. That means no references whatsoever. Your only reference during the exam is limited to the provided NCEES Reference Handbook PDF shown on your computer screen.

As for the current Pencil-and-Paper format, yes, you need an official ID, and you are not allowed any electronic devices including cell phones, computers, fitness trackers, or smart watches (wristwatches are okay). However, you will have your personalized reference materials and approved calculator (and spare if you like), and you can bring in two straightedges (such as a ruler, scale, triangle, or protractor) and handheld magnifying glass. You can even have snacks (hard candies, candy bars, and even gum which is restricted in the CBT facility) and nonalcoholic beverages. You can essentially set up a home away from home for the duration of the exam. I remember having a bag with morning goodies to eat and drink and then a separate bag for the afternoon. I know the chocolate yogurt flavored raisins I consumed during the afternoon portion of the exam were a key to my success. Not a chance having those in a Pearson VUE testing center, except during your timed 50-minute lunch break.

If you like “rules”, then you are going to love the new CBT format. If not, then if you don’t pass the PE Exam before these changes take place, you will have no choice but to comply with a great many rules.

3D Printed Bandshell

One of the big challenges in designing large structures is the time and cost of building prototypes. Tall buildings often have small models for wind testing, but forget about anything close to full scale. The time element of building prototypes has been reduced thanks to the invention of 3D printing, but now engineers in Nashville have used it to build a full-scale, permanent bandshell that’s 20 feet tall! The bandshell meets relevant building codes including wind, ice, and snow loads leaving one to wonder if we'll soon have a new manual for plastic structures. - Shannon Warchol, DTC Civil Structural Instructor

The CBT Exam Experience Versus the Pencil-and-Paper Exam Experience


In this installment of my posts on the scheduled transition to Computer-Based Testing (CBT) format for the Mechanical PE Exams in 2020 and the Civil PE Exams in 2023 (https://ncees.org/exams/cbt/), I want to look at the difference in the experience of taking a CBT PE Exam and taking a Pencil-and-Paper PE Exam. Understanding the difference is an important consideration, because, for many people what keeps them from passing is the nervousness generated by the exam experience itself and not their lack of understanding or ability to solve problems. 

One key change in the exam experience is that the CBT format uses what is called Linear On The Fly (LOTF) testing, meaning that each examinee will get a different exam. Currently, when the NCEES administers the Pencil-and-Paper PE Exams, everyone in the country takes the exact same exam in their discipline. Yes, the questions for one exam cycle will be different from another, but everyone is facing the same changes each time. However, with the CBT exam, you might get a lot of questions in an area you are not very familiar with and the person beside you, or one who comes in another day, gets just the right number of questions in the areas they are familiar and very few in their weak areas. This sets up a much bigger “roll of the dice” factor, and I have a “minimum of high regard” for that philosophy of testing. It will, however, be the case for the CBT format.

If that doesn’t make you nervous enough, then watch the NCEES YouTube video showing what will happen when you arrive at a Pearson VUE Testing Center to take your exam. The sight of someone having to pull out all the pockets of their pants and do a 360º turn in front of the administrative assistant is a bit disconcerting. The assistant is smiling, but the adversarial nature of the things you are required to do is unnerving, to say the least. First, you read the rules, show an approved ID, provide a digital signature, have your picture taken, and then provide a palm vein scan. You are told to put everything but the few allowable items into a locker. Next, another ID check and palm vein scan, and you are given your work pad and pen and escorted to the testing room door where you are to read, yet again, the rules. You are then escorted into the small testing room and the cubicle where you will spend the next eight hours taking the exam, carefully watched by a proctor over security cameras. At your cubicle, you watch a short tutorial on how to proceed with the CBT exam, then the clock starts and will literally count down the seconds until your time is over. You can take breaks (palm vein scan going out and coming back), and you are intensely watched so that if you access your locker you don’t violate one of the rules. There are numerous security procedures that you must follow precisely or your exam will be invalidated. You can learn more about the new CBT experience from a series of NCEES videos.

In contrast, for a Pencil-and-Paper exam, you arrive along with hundreds of other people and are shown to a large table in a very large open auditorium where you can begin to set up all the references you have brought. Yes, no cell phones or computers, but you can have just about anything else including food and drink, though at some locations these are restricted. In the CBT cubicle, you can’t even chew gum. In the pencil and paper environment, there is an air of excitement and expectation, that you are part of a bigger world. Yes, you are sitting in a pre-assigned seat and someone asks for your ID, but that is it. You sit waiting for the exam to begin among a great many others with the same ambition of becoming a PE. Instructions are read to you by a person at the front of the room, usually at a podium. A team of proctors circulate, helping people get settled. Professional, but very friendly. During the exam, if you have to use the restroom, you simply raise your hand. Once the Pencil-and-Paper exam starts, there is a big clock on the wall and periodically the time remaining will be announced. Again, none of the intimidation generated by the CBT format. 

Those are my impressions of the two vastly different exam experiences, and the Pencil-and-Paper exam wins hands down in my book. I can tell you that without a doubt I would not be looking forward to taking the exam under CBT format conditions. I would like to think that it would not affect the outcome, however, I am sure my stress level would be maxed out during the entire experience. If the CBT experience does not appeal to you, then your only option is to take the Pencil-and-Paper PE exam now and pass!  Once the change has been made to the CBT format, there will be no other options.

Time Perception and Ferry Queues

One of our DTC instructors, Dr. Daniel Findley, recently led the publishing of a paper in the Research in Transportation Economics Journal on a project about the North Carolina ferry route from Hatteras to Ocracoke. The paper examines observational data from a wait-time study at the ferry terminals to demonstrate that the amount of time a vehicle waits to board a ferry is highly dependent on that vehicle's position in line. Queue psychology suggests that unexplained waits, uncertainty, and anxiety make wait times for individuals seem longer. Thus, the vehicle position and wait time relationship can be used to equip ferry service providers with the knowledge to inform and improve passengers' experience waiting to board a ferry.

FEATURED TESTIMONIAL - Benefits of an Online Course

“After two failed attempts, I believe that Dr. Tom's course was just what I needed to get on the right track. I found out about the course from the free YouTube videos, and I was sold on the presentation style; confident and up-beat, very unlike the other course DVDs I had purchased before. Having never taken an online course, I was initially very skeptical. After taking Dr. Tom's course, I realize the many benefits of an online course. There is great value in being able to pause, back up watch the material multiple times if you need to do so. Because of the course, I was able to solve a difficult vibration problem with damping; the type of problem I may not have attempted otherwise. I have recommended the course to a young engineer I know who is planning to take the PE in the near future and will continue to recommend the course.”

CBT Means No Personal References During Exam


In this second installment of my posts on the scheduled transition to Computer-Based Testing (CBT) format for the Mechanical PE Exams in 2020 and the Civil PE Exams in 2023 (https://ncees.org/exams/cbt/), I want to focus on the change that will have the most significant impact on the exam experience and your ability to prepare for the exam – the restriction on taking personal references into the exam.

In the long history of the PE Exam, you could bring almost any personal reference to the exam facility. I remember when I took the exam many, many years ago, a fellow examinee rolled in with a steamer trunk full of books. In the face of that long-standing tradition, the upcoming transition to the CBT format is very disconcerting indeed. In this new format, you will not be allowed to take a single reference to the exam with you.

Not one!

Instead, you will be presented with a searchable PDF of the NCEES Reference Handbook, sharing half of the 24-inch computer screen with the PE Exam itself. And this reference is likely to be many hundreds of pages long. For the Chemical PE Exam, the Reference Handbook is almost 600 pages. The thought of getting to be familiar will 600 pages of information is almost incomprehensible, and printing it out gains you little or nothing, because that’s not how you will have access to it during the exam.

With the old format, which is now referred to as a Pencil-and-Paper exam, the process of assembling the reference materials to take into the exam was a vital part of your preparation. Deciding what to take and preparing your references for easy access to information, required much thought, resulting in better retention of that information. I have seen this consistently in many years helping engineers to pass the PE Exam. The more effort our students put into preparing and organizing their references, the better they do on the exam. Beyond the exam, the materials you generate in preparing for the PE Exam are also materials you can use once you became a licensed professional engineer. It is unfortunate that the CBT format will make that effort obsolete. No longer will you be able to enter the exam with the sense of confidence and accomplishment that you had collected, created and brought to the exam the materials that you needed to succeed, and leave with a wealth of materials you can use in your life as a PE. I’m afraid that, instead, there will now be merely a sense of just surviving the CBT exam experience.

There is clearly an advantage in preparing for the PE Exam with materials you gather and create yourself, as well a great reward in passing the PE Exam knowing you were the one who compiled the reference materials. And for these reasons alone, my advice is to take and pass the PE exam now, before the change takes place!

Take Two and Text Me in the Morning

For some time doctors have come to know that what happens to the food we eat is of paramount importance to our health. More and more research is being conducted specifically on the gut, the stomach and the smaller intestine. Obtaining accurate data on what is actually happening has been illusive.

In a recent New Atlas article, doctors at RMIT in Melbourne, Australia have developed a device that when swallowed can send back data on the gases circulating in our system. Previously, these gases had to be detected by using a breathalyzer.  With this new device the data is transmitted wirelessly in real-time over Bluetooth to a smartphone. Once it has done its job, it passes safely through the system.

Doctors see the possibility of this type of device diagnosing all manner of diseases so that in the very near future someone seeing their healthcare professional will actually have them say, "Take two of these devices and they will text me in the morning."  As they say, "What will they think of next?" - Dr. Tom
