Thank you both for your feedback.
2. ## NCEES vs. PPI Practice Exams

Thanks for the feedback and well wishes! Yes, slightly newer to the forums. I had seen passing mention of the format change, but it didn't hit me until 1 week ago when I took the PPI exam after the NCEES exam. What do you think the rationale was behind the format change? I agree that it seems like a step backward.
3. ## NCEES vs. PPI Practice Exams

Thanks SacMe24. Johnny, I was frustrated / surprised to learn this 2 weeks out from the exam. I had ordered all of my reference materials this last spring. MERM's outline of course reflects the old test format, so I spent most of my time on fluids and MD&M, with a sprinkling of other, just to now find out much of it was for naught. Considering this change was made 1.5 (or more) years ago, I am frustrated that PPI did not communicate this at any point, even with a flyer inserted into MERM.
4. ## NCEES vs. PPI Practice Exams

Just found the thread on the exam format change(http://engineerboards.com/topic/27390-new-mechanical-pe-specifications-for-the-april-2017-exams/) and this now makes sense. With that being said, besides the 2016 NCEES practice exam, what is another practice exam that people recommend that I can take that is reflective of this new format?

Hi Dr. Woop, Thanks for your reply and for sharing, I appreciate it. With that being said, can you comment on the fundamentals of my question as it pertains to the PE exam? I think that the total area is used for calculating the direct shear (F/Atotal), but still don't understand the difference between why you would use J=0.707*h*Ju (seemingly to evaluate max torsional shear at an extreme fiber) vs. J=Total Weld Throat Area * Ju (ie two parallel, vertical welds each of length d, would be J= 1.414*h*d*Ju )
6. ## NCEES vs. PPI Practice Exams

I am taking the Machine Design & Materials Mechanical PE Exam in less than 2 weeks. I took the 2016 NCEES practice exam a week ago and passed. I generally felt that it was a "good fight" and some problems I knew, some I figured out, some I struggled with and made educated guesses. I studied my errors and if I took that exam again, I know I would have done much better. On Friday (2 days ago), I took the 2016 PPI Mechanical PE practice exam. I haven't graded it yet, but I did miserably. It was not a good fight. I was crushed, largely by the morning breadth section. There was TONS of psychometrics, HT, etc that I haven't practiced as much. So, this being said, the question is what to do for the next 11 days. I have almost unlimited time to study. When I compare these two different exams, they are fundamentally so different. The breadth section of the NCEES exam, was geared toward MD&M. When you look at the "Exam Specifications" in the NCEES practice exam, they describe the morning section as "Principles", including basic engineering practice, material properties, strength of materials, etc. Things you would expect from a broad overview of MD&M. There were really no psychrometrics, HVAC, HT, Thermo or fluids in this morning section (maybe 1-2). The PPI morning section seemed to be breadth in the sense of anything that a ME would study in college (including HT, pyschrometrics, etc.) and because I hadn't focused (apparently) enough in those topics, I did very poorly. The question is, what is the actual PE MD&M exam like? I am obviously hoping that the NCEES exam is what it will be like. If this is true, I would then keep mostly (80%) focusing on MD&M and the balance on everything else. What is so odd is that as PPI is a leader in this field, how could it be so far off from the NCEES exam? Thanks.

Thanks Sac & Audi. After posting, I then went and looked at the delta in the exam results forum and it seems like 5-6 would be a safe average.

Can anyone comment on the average time after the exam to find out if you passed or failed? MERM states 8-10 weeks, hoping they aren't that incredibly slow in grading a scantron.

Thanks Monty!
