DTC Review for the Mechanical PE Exam:


If your work experience involves fluid mechanics, thermodynamics, HVAC or refrigeration, the Thermal & Fluid Systems PE Exam is the right exam for you. Even if these areas are not your strong suit, you should consider taking this exam. It’s easier to prepare for and we can get you up to speed on these topics. – Dr. Tom

Before you choose the Thermal & Fluid Systems Exam as your PE Exam, we recommend that you watch Dr. Tom’s Mechanical Exam Strategy – Part 1 Video to see Dr. Tom’s recommendations on Exam choice. 

Signing up for the DTC Review for the Mechanical: Thermal & Fluid Systems PE Exam gives you access to Dr. Tom’s successful, exam-focused, online course from the day you sign until the day of the exam.

“Dr. Tom’s advice to take Thermal and Fluids proved invaluable. I had originally intended to take Machine Design, but I took the Thermal and Fluids PE Exam per his advice, and I felt really comfortable. I hated thermodynamics before the exam, but he helped me understand it and become comfortable with it. Thank you, Dr. Tom”

– Abdel-Rahman Elnoubi, PE, Alexandria, Virginia

Dr. Tom’s Comprehensive 20-Week Plan

Thermal & Fluid Systems Course Structure

The Review covers targeted topics on the Mechanical: Thermal & Fluid Systems Exam, and it is based on a 20-Week review structure. Each week is devoted to a different topic and provides you with lessons and practice, familiarizing you with solutions for the type of problems you will see on the exam.

Timed practice exams throughout the course help you build your confidence in solving problems in exam-like conditions. By then end of your review, you will have the knowledge and skills you need to pass the exam.

Dr. Thomas H. Brown, PE will be your instructor throughout the course, with Dr. Daniel Findley, PE teaching Engineering Economics topics.

Three Flexible Payment Options

Try Before You Buy for Only $50!

Buying a PE Exam Review is a major purchase. That’s why we offer three flexible ways to pay for your course and save money. With each payment option, you receive the same comprehensive review; the only difference is when you pay and the overall cost.

With our Pay-As-You-Go and Test Drive options, you can try out our courses for only $50 before you buy the full course. We’re so sure you’ll like what you see that there’s no obligation beyond your initial purchase.

You can save $100 if you Pay Up Front for the full course and save $50 with our Test Drive option.

You have access to all the course materials for a full year, starting the day you purchase each module, so you can start your review immediately and work at your own pace until the exam. The ideal time to begin your 20-Week Review is 24 weeks before your exam date.

What to Expect

This comprehensive and targeted review uses Dr. Tom’s method for relearning the needed engineering concepts, becoming familiar with the Reference Handbook, and using his problem-solving strategy to maximize your ability to solve problems quickly during the exam.

Your course will be 100% online, and you can access the course materials 24/7 allowing you to work at your own pace and on your own schedule. We have also kept the course videos short (10 to 30 minutes) to give you the flexibility to fit your review into your schedule. 

In the Review, you follow detailed, day-by-day assignments in your study plan in which you:

  • go online to watch pre-recorded video lessons (over 50),
  • learn the most efficient ways to solve problems,
  • work numerous, carefully chosen problems including:
    • Lesson Problems with solution videos
    • assigned NCEES practice exam problems,
    • Challenge Problems with solution videos in the course (over 50),
    • weekly Assessment Quiz in the course,
  • access a Participant Forum to ask your instructors questions about the course content,
  • download handouts for every lesson presented,
  • use the Mechanical Reference Handbook Companion to become familiar with where to find information in the NCEES Handbook.
  • take timed practice exams throughout the course to build your confidence solving problems in exam-like conditions.

It’s a lot of material and a lot of work, but if you follow the plan, you will be prepared for the exam.
