The sheer amount of problems I worked through STPE study guide and the practice exam did this for me. There are a few non basic “shortcut” equations that are infinitely useful and one of the best parts of STPE is I felt they really went out of the way to point these out.

I liked that the On Demand course was similar to a college course, it was almost a semester (~4 months) long. There was literature for reading, pre recorded videos to highlight important topics, and practice problems (homework) for each section. I won't bullshit you, it was a lot. But for me that's the type of plan I needed to be successful.

Slay the PE (STPE) is definitely the way to go for TFS exam prep. I am a non-traditional student, turned welder, turned Engineer, with family, bills and a mortgage, and with that being said, can say that STPE created a very doable workload that involved adhering to a customized study schedule that didn't wreak havoc on home life.​

The study guide was great--it explains all topics in a very practical way--I used it a lot for my job as well. Its very well researched and written.

The study guide and practice material still managed to exceed my expectations. The study guide explained topics in a concise and clear manner, without delving too far into the weeds on theory not relevant to the PE exam... focused on exactly the curriculum that was most prevalent throughout the exam.

Big shoutout to SlaythePE for pushing me along these weeks and keeping me on track to pass on my first attempt... This is the only resource I used to study besides the NCEES practice exam... I followed this plan pretty much to a tee, and by the end of it I scored an 80% on the NCEES practice exam...

Slay the PE is the only way to go. They just over-prepare you in the best ways possible. They walk you through how to do the toughest problems you could realistically anticipate showing up on the test, in a cohesive and coherent way. They provide forums to ask others if you don't understand something. They CONSTANTLY check in on your progress - through email, diagnostic exams, you name it. If I designed my own TFS course, it would look almost exactly like Slay the PE's.

I used Slay The PE On-Demand Course. If you would like to pass this exam, you’re doing yourself a disservice not taking this course.

SlaythePE helped me out tremendously. Wouldn't have passed without them.

I highly recommend the Slay the PE mechanical TFS study guides. For information, my undergraduate is in Nuclear Engineering...

I highly recommend Slay the PE. It's where I truly understood concepts and theories that I never fully grasped in college. They simplify complex topics and explain them in a way that's easy to understand, making it much easier to build a strong foundation.​

(Slay the PE) broke the concepts down very well and the study schedule they provided kept me on track, so I didn't have to figure out for myself what I needed to study or review. I really hadn't done much Heat and Mass Transfer or Thermo since college, but taking this course really helped me get a strong grasp of the fundamentals.

The only resource I used was Slay the PE. If you’re like me and like to compare your circumstance to others here is mine; B.S. ME from a solid engineering school almost a decade ago, haven’t touched anything quantitative since.​

I want to give a shoutout to Slay The PE for the study materials and pretty much providing the keys to success for this exam.

I passed the TFS PE first attempt. I graduated back in 2019.

My primary study resource was Slay the PE. I can’t recommend them enough. The text / practice problems were excellent in learning the core material...
​
The customer support was also very helpful whenever I had a question and the responses were always very thoughtful and I always received a response in a reasonable amount of time.​

I passed, I can hardly believe it. Graduated in 2013. Slay the PE is phenomenal. My sole source of studying.

The course being on demand makes studying very convenient for someone like me that works and has a family... the information was presented in a way that was easy to understand."

"Slay the PE adequately equipped me with the information to solve those problems and that is what ultimate led to me being successful.

SlayThePE is really all you need to pass​... I didn’t encounter many questions on the exam I didn’t know how to solve thanks to Slay’s course... [The exam] wasn’t easy but was doable, and a lot of that came down to the perfect preparation SlayThePE does.

Got my results this morning, passed Mechanical: TFS 1st try! ...huge shout out to SlaythePE for being my primary studying resource.

Used Slay The PE for my third attempt. Anyone looking for a prep course for TFS, I would only recommend Slay... They really helped me understand subjects instead of me trying to search for an equation in the mechanical reference handbook. They were able to break down subjects that seemed so complex...
