"Dr. Tom's 20-week review course was very helpful at breaking down the mountain of information that is Mechanical Engineering into small bite-sized pieces. I had taken the PE twice before, and my biggest concern was problem identification and time management. I knew that these two strategies are critical to passing. On previous exams, I often times would not be able to quickly identify the question type and, therefore, wouldn’t know how to begin to solve it. I believe this was the main reason I did not pass before, and the other review course I took did not help out much with that. It was apparent early on in Dr. Tom’s 20-Week Review course that problem identification was one of the main focuses. With the way the course topics were divided, as well as with use of the Personalized Resource Notebooks, I was able to identify problem types significantly faster than before. I believe this was the main reason I passed. Dr. Tom seems to really care about his students and course attendees, and I’m grateful his devotion has lead to such an effective review course. Dr. Tom’s course was much more effective than the other review course I took, and I would recommend Dr. Tom's 20-Week Review to others preparing for the ME PE Exam, without a doubt. William Allred, PE, LEED AP BD+C, RS&H, Merritt Island, Florida
"My experience with Dr. Tom's practical focus on application of engineering principles in an undergraduate course at NC State University allowed me to make an easy choice in Mechanical Engineering PE exam preparation courses. His no-nonsense approach coupled with a wide-ranging experience and clear explanations validated my pick and was undoubtedly a key factor leading to my passing score on the Thermal/Fluids exam. The well-structured course format provides an organized progression through the review material and the resources provided were key in my ability to efficiently work through the exam. The MERM and Dr. Tom's Exam Day Companion were the two references I used for about 90% of the problems. With better than competitive prices, effective teaching ability, and proven results, Dr. Tom's Classroom is undeniably the best value in Mechanical Engineering PE exam preparation, thanks Dr. Tom!" Andrew Lipetzky, PE, Duke Energy, New Hill, NC
"Dr. Tom's 20-Week review was immensely helpful towards my success on the PE exam. I realized early on that I would not be able to maintain a studying schedule on my own and am glad I took his course. My other main concern was being able to understand the concepts well enough to quickly understand what the exam problems were asking. The online lessons were the especially helpful because they explained concepts that can be confusing in other resources (like the MERM) or difficult to review on your own. The lessons are easy to follow, and Dr. Tom's teaching style gets right to the point. He teaches you what you need to know and what not to waste time on. His dedication is obvious and he makes an effort to answer every question. I would recommend this class for those who like to take their time studying and especially for those who need a good refresher course, but it's up to you to put in the effort." Angela McNeely, PE, Overland Park, KS
"Being nearly 20 years out of college, I was VERY intimidated to attempt the PE exam. I can say with absolute certainty that Dr. Tom’s review course was the key to my success. The organized approach (study schedule, practice problem selection, and reference binder structure) allowed me to focus on learning the content for the exam instead of wasting time trying to figure those out on my own and just studying the MERM. I was doubtful that I could get back up to speed on so many of the subjects that I spent years studying in college, but it worked! I initially was planning to attend a live class offered by another company. However, sitting through 4 days in a row of 8 hour classes (for three weekends) did NOT appeal to me or fit my learning style. Tackling it at MY pace and on MY schedule (weekday lunch and evenings, weekends), focusing on solving examples, and shoring up trouble areas before progressing to new lessons was the only way I could effectively learn the material. Doing, not merely watching is the key for me. Having the same teacher across all subjects was also a plus, as was the fact that Dr. Tom's classes are less expensive. Dr. Tom's Fast Track Review has an aggressive schedule. However, I worked hard (30-40 hours a week) to "knock off the rust" my skills had collected over the years and get caught up. The classes reminded me of college lectures, except focusing on the applications instead of developing equations. Let's just say I was even knocking the rust off of my ALGEBRA skills when I began the course and still covered enough ground to not only pass but score a "B" on the exam. I would recommend Dr. Tom’s Reviews, but due to time demands of the Fast Track Review, for those juggling work and family responsibilities, the 20-Week Review may prove a better fit. But I can't argue with the results!" Brent V., PE, Houston, Texas
"I knew I wanted my P.E. license long before I was eligible to take the exam. I've never been a great test taker. I definitely didn't graduate at the top of my class. I always had a problem with the time limits imposed on me in college exams and knew that the P.E. was going to be no different. When I got my four years of engineering experience, I immediately started looking at the resources available for me to prepare for the exam. I came across Dr. Lindberg's Mechanical Engineering Reference Manual and immediately saw that I had a lot of information to cover in order to be prepared. I wasn't even sure where to begin. I didn't know which pm exam was right for me. The one thing I did know was what it felt like to fail an NCEES exam. I was one of the statistically low number of "first time takers" who didn't pass the F.E when I was fresh out of college. This would be my first try at the P.E. exam, and I really wanted it to be my only try. After looking at all my options, I decided that a prep course would be the best option for me. I liked having a structure and liked the idea of being helped by people who dedicate themselves to helping guys like me pass exams. Many of the prep course options seemed a little impersonal to me and offered very few samples of the course content that they offer. I noticed Dr. Tom was much more generous with his content and explained himself very clearly. I was pretty much sold after I saw his videos on exam strategy. No one else was offering anything close as far as free content goes. It's also hard to go wrong with a southerner. ; ) Dr. Tom's course had a solid plan and he was always available to answer questions. His course requires a lot of time and work, but he was there with us every step of the way. By the time exam day came around, I was very prepared and felt I had a realistic chance of passing this exam. I had no idea what the NCEES would ask me, but I knew I had a strong foundation to face what was coming. I took the exam using Dr. Tom's strategy and was able to finish with enough time to check my work in both the AM and PM portions of the exam. Nothing was able to calm the nervousness that I felt waiting on my exam results, but I did leave feeling like I at least had a fair chance of passing. After weeks of waiting nervously, I got my results and found out I passed. The pressure has been lifted and I'm excited to move on with my career and personal life. I would recommend this course to any mechanical engineer who is serious about giving themselves the best chance possible to pass the P.E. exam." Brian, PE, Taylor Machine Works, Starkville, Mississippi
"As a Military member taking the ME PE, I didn't have any other ME PE's around that could offer me specific advice on how to study or what to study for the ME PE. If you are an ME looking for a PE review course, look no farther. Initially I didn't think I needed a review course, after all I passed the FE without studying at all and have 2 Masters in Engineering. On my first attempt at the PE exam I gathered all the recommended materials I could find, established a system and devoted 260 hours to studying. I failed. Too much of my self directed study time was spent studying high challenge low probability material or material that wouldn't even be on my depth portion or the exam at all. Dr. Tom provided strategy, guidance and clarity on what to expect on the exam as well as well organized high quality review material and videos. I re-doubled my efforts and after another 415 hours of studying I retook the exam and breezed through it. My advice, if you are going to devote that much of your time to studying, spend the money for the review course. If I could go back in time I would spend 10 times the cost of the review course to take it from the start. I have no doubt I would have passed the exam the first time if I had taken Dr. Tom's review course. Don't spend 400 hours kicking yourself for trying to save a few dollars, just take the course. After all, how much is your time worth to you?" Brad Townsend, P.E., MAJ USA
"Dr. Tom’s class structure simplifies preparation for the exam and provides great tools (Personalized Resource Notebooks and Exam Day Companion) that were extremely helpful during the exam. I would definitely recommend others to consider this approach." Jose Chavarria, PE, DNV GL Inc., Phoenix, Arizona
"I finally passed the PE exam! I give credit to Dr. Tom and his course. His assistance and being patient with my questions helped guide me in my study and achieving this goal. I was hesitant to take the Thermal/Fluids exam because I didn't have the background in Thermo. Then I found Dr. Tom's course and his exam analysis to take the Thermal/Fluids exam convinced me. So I took the leap of faith and it was the right choice. I lacked organization. We all know the vast material to cover, but I needed someone to help me focus on the major exam topics. Dr. Tom did a great job in addressing the key topics. Comparing other PE Exam preparation courses I have taken, Dr. Tom's course was very organized and concise and focused. Dr. Tom was very committed, and I think he enjoyed it and liked helping us achieve this goal. I would definitely recommend Dr. Tom's 20-Week Review." South Carolina PE
"Dr. Tom's 20-Week Review helped immensely. I had taken a different review course previously, but didn't pass. I was unsure if another review course would help. I liked Dr. Tom's course because he provided test taking tips specific to the P.E. exam. His review helped me to focus on the afternoon portion of the test. This was key for me. Dr. Tom is very committed and genuinely interested in helping you pass." John Kilgore, PE, Mantech, Huntsville, AL
"The structure and support that I received from Dr. Tom's Classroom was paramount to my success during the exam. The exam strategies provided by Dr. Tom coupled with the Exam Day Companion kept me focused during the exam, allowing me to scoop up as much "low hanging fruit" as I could on my way to passing. I initially was more comfortable with the prospect of taking the Mechanical Systems portion of the exam, however after hearing Dr. Tom's pitch for the Thermal Fluids portion of the exam, I switched gears, and I could not have been more pleased with the results. The live instruction and 1-on-1 Q&A provided by Dr. Tom helped to calm my nerves about the exam as well as build confidence in my ability to pass. During the first meet and greet portion of the live classroom, I had a nice discussion with Dr. Tom that set the tone for the PE exam process and put it in great perspective. He told me that the purpose of the PE exam wasn't to measure your value as an engineer, but rather just your ability to pass this specific test. I truly appreciate the efforts put forth by Dr. Tom and all others that make this review possible. Being that there is less focus on the Mechanical PE exam vs the Civil PE exam, I was happy to find people who cared about me and my success on the exam. I have had several colleagues ask me how I prepared for the exam, and even though they are Civil engineer's, I tell them about Dr. Tom's Classroom, the structure and support it provided, and tell them to find a review course like it. Without hesitation, I would tell any ME preparing for the PE exam to start with Dr. Tom's Classroom." Chris, PE, Toms River, New Jersey
"Students can always spot a teacher that cares about their success, and it's apparent with Dr. Tom. It's obvious that Dr. Tom has many years of teaching experience, and his lessons are well planned and communicated. There is no magic bullet for passing this exam, but if you're willing to put in the work, the 20-Week course is invaluable." Michael Kruse, PE, Florida
"It had been 18 years since I graduated with my BSME, and I knew I had a huge challenge ahead of me to review and re-learn all the necessary material. I had tried just studying from the “big blue book,” and I had looked into other review courses as well. I chose Dr. Tom having seen how he presented material in his sample videos. Once I began the course, I knew I had made the right decision. Dr. Tom will focus your study on what you need to know, he will take the time to explain those elements which are challenging, and he will be there all the way through to exam day. The materials that Dr. Tom provides are invaluable during the exam! I honestly believe that I could not have passed the exam without Dr. Tom’s teaching, guidance and strategy. Dr. Tom should be your #1 resource for exam preparation!" Mike R., PE, Atlanta, GA
"I passed the April 2015 exam, after failing the exam for the first time in October 2014, 7 years after graduating from NC State. Both times I took the HVAC and Refrigeration exam, as that is the field in which I am working. The first time I took the exam I studied on my own, primarily going through the MERM mostly and not working enough problems. The second time, I followed Dr. Tom's 20-Week online only study plan as closely as I could with some modification due to my schedule. The structure that his lessons and accompanying problems provided was very helpful in refreshing my understanding of the concepts in each topic presented. There were even a few of his example problems in the April exam, so those problems were much easier to navigate. I did start out a little late with the review course, and I had to catch up, but I was able to stay on target week after week after that. On the exam, I found that I didn't use the DTEC as much as the PRNs, however both were useful. All in all, having the information organized was a great help! I told my uncle who is an ME NC State grad about the review course I was taking and mentioned Dr. Tom. He said that Dr. Tom taught him Statics during his time at school in the mid to late 1980's, and that I should do very well, given his insistence about always using units to help solve problems. I found that Dr. Tom's explanation and break down of the conversions was also helpful in learning how to work through the problems. Overall, going into the April exam I felt very much more prepared than the first time taking it in October. In fact, the April exam seemed "easier," which I can accredit to using Dr. Tom's review course. Dr. Tom, thank you for your course and the passion that you display while teaching it." Ryan Crawford, PE, Mebane, NC
"I previously took the mechanical systems exam and failed 3 times, but after taking Dr Tom's 20-Week Review, I passed it right away!" PE, New Hampshire
"The most valuable aspect of the course for me was that Dr. Tom provides a finite range of material to study, so that I did not have to guess about what might be on the exam. That alone was worth the price of the course. It also helped me to have the structure of the course to follow. I am a teacher myself, and I recognize that Dr. Tom is personally invested in the success of his students. He puts a lot of thought and work into providing good instruction. Dr. Tom and staff, thank you so much for all of your help." John Gravitt, PE
"The structure of the course worked well for me. My concerns revolved around the spectrum of topics to review. While it seems overwhelming, it was nice to focus on the topics in one week “chunks” and to have the decisions already made for me as to what to study, when to work on it and targeted problems and chapters already noted. This allowed me to set aside some anxiety as to topics of greater importance. I specifically found the unit conversions and references to material in the MERM helpful, and the suggested organization for reference material was much appreciated. Dr. Tom’s level of commitment was easily displayed by his videos. The extra effort taken to purposely break down the steps, equations and unit conversions was beneficial to me. Also, adding the background commentary to real-world problems that he encountered was an added bonus. It was nice to hear about real-life usage of the topics being discussed. I would recommend the course to others." Walt Herbert, PE, Baldor Electric Company (A member of the ABB Group), Greenville, SC
"Preparing to take the PE exam 20+ years out of an undergraduate program is a daunting task. What information is relevant? What strategy should one follow? Perhaps most importantly, where does one begin? I was happy to find Dr. Tom's course as it provided me with a more relaxed window of study (20 weeks) necessary to focus on relearning and practicing lost knowledge. The courses are concise, and his notebooks contain the necessary formulas with just enough background information for wide-ranging applicability. The way in which Dr. Tom organizes the material is particularly useful when it comes to exam day where you'll want to minimize time spent searching in favor of maximizing solution time. This course, coupled with some practice examinations will ensure your success." Scott Rapoport, PhD, PE,  San Diego, CA
"Dr. Tom's course was essential to my success. I required 'substantial' review to say the least, and in attempting to review on my own, I found myself constantly moving backward toward more fundamental studies. This method resulted in an unrealistic scope of work with no clear path for studying. With Dr. Tom's course I finally found a solid starting point and could stop spinning my wheels. I was concerned about what to study and what not to study. Dr Tom addressed these concerns directly and explicitly, problem by problem, lecture by lecture. The course carried me through to the very end allowing me to focus only the relevant and most important PE exam content. Dr. Tom's teaching is, and not surprisingly, very professor-like and primarily lecture based, which is exactly the environment I sought out. I needed that teacher-student dynamic to re-familiarize myself with even some basic concepts, not to mention to more advanced ones. With his help, I passed on my first attempt. I would recommend for this course, especially to those that enjoy the virtual classroom-type of instruction. Dr Tom's course content alone is worth the price, but the real value for me came from having a rock solid structure that I know is absolutely tailored for the PE exam." Tommy S., Las Vegas, NV
"Dr. Tom's 20-Week Review was absolutely critical to my success on the Exam. After being out of school over 11 years, I couldn’t have done it without a review course. I considered other review courses, but felt that Dr. Tom’s would be much more personal. Dr. Tom does a great job giving every student the personalized help that they need. His teaching was excellent, and his commitment my success was top notch!  I wasn't sure which exam to take, and Dr. Tom covers that well. The class was a great review for the PE and also very helpful in just getting back up to speed on some topics. I would absolutely recommend Dr. Tom's 20-Week Review to anyone preparing for the ME PE Exam!" Adam Jones, PE
"I feel like Dr Tom's class was instrumental in helping me pass. When I attempted a few years ago, I bought the MERM and my goal then was to read each chapter and work the problems. I started for a few weeks and gave up. After being out of college for 10 years, I needed a tool to help me get back to being motivated on the subject matter.  How I used my time wisely to study was a major concern for me. I work a job and have other commitments that requires 60-80 hours a week of my time.   Dr. Tom's 20-Week Online Only review course quickly got me on task and provided the study plan I was looking for to pass the exam. The structure and repetition of the online review put me in the frame of mind to concentrate on studying. From the beginning, Dr Tom lays out what's going to be required to pass the exam. I found that extremely helpful. Knowing what kind of commitment you need to pass and reviewing the structure of the exam laid out the foundation for each of the next weeks programs. The weekly guides on how to manage your study week provided a nice checklist. Having multiple lessons and problems to review each week gave a full depth of knowledge on each of the subjects required in the exam. The passion Dr. Tom has to help people succeed on the exam shows in each of his lessons. He is very detailed and explains every part of the problem, providing practical questions/answers using real world applications. I would absolutely recommend Dr. Tom's review course! It's perfect for someone looking for help to push them along and keep them dedicated on studying to pass the exam."  Adam Sippel, PE, Brady Sales and Services, Raleigh, North Carolina
"I have a unique insight to Dr. Tom’s philosophy on exam preparation.  I attended NC State University about 20 years ago where Dr. Tom was my instructor in an instrumental review class intended to get one ready for the FE exam.  He was able to sum up four years of education in a succinct way that most people cannot.  He got me ready to pass the FE on the first try. Jump forward a couple of decades and I had let life get in the way of sitting for the PE exam.  Being out of school that long, I certainly was not prepared to jump into a rigorous 8-hour exam that would encompass my career and many items I had left behind as a distant memory years ago. Discovering that Dr. Tom had taken his class to the land of cables and keyboards, I was very relieved.  I knew that if anyone could get me ready again, it would be Dr. Tom.  Starting the class, I immediately knew it was the same old Dr. Tom.  No non-sense, make the plan, work the plan kind of guy.  He is the kind of guy that knows what a slug is, and knows when you should use it.  If you want a plan that will put you on the track to first time success, Dr. Tom is your man."  William Lowery II, PE, UNC Cogeneration Systems, Chapel Hill, North Carolina
"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 You tube 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 on-line course, I was initially very skeptical. After taking Dr. Tom's course, I realize the many benefits of an on-line 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."  Bill, PE from Texas
"I highly recommend anyone contemplating the ME PE exam consider Dr. Tom's 20 week PE Review Course. I passed the exam on my first try in April 2014 after completing the online-only course over the winter. Dr. Tom's Exam Day Companion was my main (almost exclusive) reference. I only used the Mechanical Engineering Review Manual for its tables and figures. In fact, these were the only two books I opened during the entire exam. I'm sure many candidates have passed without the level of support Dr. Tom provides. Unfortunately, at 20 years out of school, I needed a structure to optimize my time studying. Dr. Tom's course provided all that and more." Jim Haddock, PE, B&V, Overland Park, Kansas
"I passed with an 84%!  I am convinced that without Dr. Tom's Classroom I would not have done nearly as well and there's a good chance I would not have passed. I was very impressed with the material Dr. Tom covered, how he focused on what we needed to know for the exam (not the theory), and how open he and his staff were to any questions or problems I had throughout the courses. I highly recommend that anybody who is planning to take the PE take Dr. Tom's Classroom review courses and follow his study outline." Amy C., PE, Houston, Texas
"I totally attribute me passing to taking Dr. Tom's class and the resources he provided. More specifically, I am thankful I found his free videos on youtube that led me to his website. I took the PE (mechanical systems) in April 2013 and did not pass. I did not take any review session course but instead tried to just read through the MERM. This time, I found the Dr. Tom's Exam Day Companion (and it's index) to be invaluable. I used my resource binders, the sample exams, and the MERM as my only reference materials and I found them to be totally sufficient. Thank you for your help this past exam season. It truly was my pleasure." Craig, PE from Virginia
"There is no doubt in my mind that anyone who completes Dr. Tom’s Course will pass the PE exam." Emil J Geiger, PhD, PE, Assistant Professor of Mechanical Engineering, University of Nevada, Reno
"I have been out of college 24 years and have been twice unsuccessful taking the ME PE Machine Design exam. After reviewing Dr. Tom’s strategies, I decided to take his prep class for the Thermo and Fluids afternoon exam. The next step was to start reviewing. Dr. Tom provided a 20 week review schedule and weekly “Live Online” classes.  Dr. Tom went over the lesson plan for the particular subject, provided sample exam problems to work in class as well as out of class. He always made time to answer questions. I definitely recommend Dr. Tom’s Classroom ME PE Exam Review!" Glenn Bailey, PE,  Pensacola, FL
"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 a test 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 20-Week 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 250-300 hrs of quality prep time that Dr. Tom recommends.” Patrick P. PE, 25 yrs out of college
"Dr. Tom's review course was essential to me passing the PE Exam. He took the time before the course to help me decide which exam to take. With his guidance I decided to take the mechanical systems exam based on my background in mechanical design. His review course provided the structure I needed to focus my attention on the subjects that were tested and he was always there to answer questions if I was having difficulties. I think one of the best things about the course is how it firmed up the basic engineering principles for me. That alone has helped me a lot with my job. Dr. Tom's course along with lots of study was my ticket to passing the exam on my first try! He is a great teacher, and I would highly recommend his course to anyone taking the Mechanical PE Exam." Justin McNeel, PE, Beaumont, TX
“Dr. Tom’s class helped me immensely.  Before beginning the process, I really worried how I would fare with academia I had neglected for the better part of 10 years or how I would manage the necessary study time with all my other obligations.  Through use of Dr. Tom’s syllabus, I was able to focus my studies to those subjects necessary for successful examination versus blindly studying the Mechanical Engineers Reference Manual page by page.  All in all, dedication to the process and study of the appropriate material is necessary for success, but the support of Dr. Tom’s prep course gets at least part of the credit for my success.  I would recommend Dr. Tom’s Classroom to anyone interested in successfully navigating through PE examination preparation.  Thanks Dr. Tom!” R. Neal Grainger P.E., NC State ’02, BSCHE, Wilmington, NC
“Dr. Tom was instrumental in my preparation for both the FE and PE. When I began working toward engineering licensure I had been out of school for some time and had not yet taken the FE.  Dr. Tom not only offered his test preparation classes to me but also took extra time with me to cover topics I was struggling with. He always had time to help and was truly invested in my success. I cannot thank him enough for the time and attention he gave me during my preparation for both exams.” Matt Murray, PE, Advanced Energy, Raleigh, NC
"After putting off the PE for almost 15 years, becoming a licensed professional engineer became a necessity for my current position.  Referred to Dr. Tom's ME PE Review course by our Vice President, Troy Byers, Dr. Tom helped me not only with the test but also helped me gain the confidence in my own abilities to let go of my apprehension of the test.  He will teach you not only how to solve the problem but help you understand the principles and concepts so that you can tackle not just the test but apply your knowledge to any real world application.  Dr. Tom is a teacher and a mentor, and if you let him, he can help motivate you to do your part in passing the exam.   Thanks Dr. Tom." Avery Darren Lapish, PE, TBE, Palmetto Air & Water Balance, Raleigh, North Carolina
“The ME PE exam is a “mental marathon” and a major undertaking for anyone, especially someone like myself who had been out of school for 30 years.  I signed up for Dr. Tom’s ME PE Review course in preparation for the April 2010 exam, and passed on my first try.  I attribute this to Dr. Tom’s Classroom for reinforcing basic engineering fundamentals which were lost in my mind.  His encouragement, knowledge of PPI’s MERM, and basic drilling of problems was invaluable in my success.  I would recommend his classes to anyone who is planning on taking their PE exam.” Michael Sulva, PE, GE-Hitachi, New Units Engineering – ESBWR, Wilmington, North Carolina
"Dr. Tom's PE Review Course was incredibly helpful in my test preparation. The course helped me to prepare for the test by not only providing lessons in a variety of exam topics, but also by providing tips and practice on how to solve exam problems. In the weekly classes, Dr. Tom provided multiple example problems in a number of exam topics, as well as instructions and suggestions on how to approach different types of problems.  The weekly lessons, class problems, and extra weekly problems, combined with Dr. Tom's suggestions, tips, and step by step instructions on how to solve test problems, helped to give me the tools that I needed to pass the PE Exam." Krystyn Wagner, PE, Wake Forest, NC
