  1. I've taken the mechanical engineering HVAC exam last October and passed. The wait for the result, especially if you're not sure if you passed or fail, is worse than taking the exam. Good luck to you all.
  2. Mechanical: HVAC + Refrigeration Overall time studying: 450+ hours mostly in the 5 months leading up to the October 2016 exam and a chunk of hours in the past couple years prior to taking the October 2016 exam ... but I never took any previous exams. This was the only PE exam I have taken. I took approaching the exam very seriously and I would most likely fail if I didn't. I have solved at least 90% of the problems in the MERM (Mechanical Engineering Reference Manual by Lindeburg) companion problems and most of the sample problems in the MERM itself. I bought sample exams including NCEES exams, 6 Minute Solutions, and old school practice exam problems that are 1 hour long and have partial credit. I bought a few textbooks (like Shigley's Mechanical Design) and solved problems from those. I am sure that I have solved at least different 1,500 problems. I made eight (8) 2" binders full of notes, sample problems, charts, and tables separated by topics. 1 binder had the MERM appendix and it was much easier to look through than the giant MERM book appendix. I passed the exam.
  3. Landolakes, I would disagree. You nearly passed and have most likely increased your score with each attempt. Those 400+ hours are probably cumulative over the few times you've attempted at the exam. I too have spent a lot of hours studying and preparing for the exam (over 450), but a majority of those hours occurred within 5 months of the exam in October. I have spent a good number of hours studying on/off for the exam in the couple years prior to finally taking it. What is your discipline?
  4. I've completed 90% of the problems from the MERM companion book and I can honestly say they helped me pass the exam. To answer your question about buying all the bells and whistle: yes, all the bells and whistles will help you pass the exam. Practice Problems for the Mechanical Engineering PE Exam (Lindeburg) (13th Edition) Mechanical PE Practice Examination (Lindeburg 3rd Edition) 101 Solved Mechanical Engineering Problems (Lindeburg) NCEES Practice Exam - HVAC and Refrigeration NCEES Practice Exam - Thermal and Fluid Systems NCEES Practice Exam - Mechanical Systems and Materials Six Minute Solutions (Elder) (2nd Edition) Mechanical PE Exam - How to Pass On Your First Try (Shepherd) Study Guide for the HVAC and Refrigeration Portion of the Exam Mechanical Engineering 175 Problems and Solutions (Pefley) (6th Edition) The more problems you do, even if they are the old school 1 hour long problems, will help you pass the exam. Also, do problems from textbooks and manuals, not just specialized practice exams. Also, take any useful charts and graphs that might be better (or might not even exist) than those found in the MERM and put them in your binders. Don't expect all the answers to be found in MERM --- you should bring other textbooks, codes, and standards that literally have the answers that are nowhere to be found in MERM.
  5. I took the October 2016 HVAC+R exam and passed it on the 1st try. There's good news if you did poorly in the other 2 categories (Thermal/Fluids and HVAC+Refrigeration). The problems from those categories will not be on the April 2017 MD+M exam. http://ncees.org/wp-content/uploads/PE-Mech_Machine-Apr-2017.pdf However, expect to see more difficult problems in the morning session. What worked for me: 8 tabbed binders with notes, sample problems, MERM appendix, and important charts. Studying over 5 months (and on/off studying before that, but never taking the exam) and over 450 hours Bring textbooks (I even brought Shigley's), codes, and standards. Do lots of practice problems, even from textbooks and old school practice exam problems with multiple parts. MERM is still important, even if the material on the April 2017 exam has been reduced. Mark's Standard Handbook is valuable, you can count on it helping you on at least a couple problems. You need to relearn some things yourself. You cannot depend on the course to carry you through.

  6. Congratulations. Studying for 50 hours would get me a "failed" result and this would apply to many others. Not everyone is as good at taking exams, have the greatest memory or knowledge of the topics on the exam as you. For the non-outlier exam takers like me, I would encourage those that want to pass the exam to take it seriously.
  7. I have about 9 years of experience in the architectural/engineering field. I have seen most of the spectrum of project management. The best project managers are very open about the projects in allowing input from the project members, giving updates on the project, and don't setup their projects to fail.
  8. Good observation. This simplifies the fluid mechanic and thermodynamic questions on the HVAC+R exam. Project management is important, but if the problems are focused on something project managers would easily answer and has nothing to do with engineering in the practical or theoretical sense, I would disagree. To me, project management fails when the project manager sets wild, unrealistic goals and tells no one about it. I've never been a project manager, but I've called out blatantly obvious "promising the moon" situations as soon as I saw them. I thought the PM average difficulty per problem was greater than the AM average difficulty per problem, even if a couple AM problems were written in Chinese (in a figurative sense). I finished the first pass of the AM problems with 90 minutes left. I finished the first pass of the PM problems (HVAC+R PM exam) with about 40 minutes left.

  10. The exam has no correlation to how well you do your job.
  11. The good and the bad of 3 completely separate exams vs 1 common AM and 3 separate PM: Good Less material and topics to study Units are all in English (at least for HVAC and Refrigeration) No project management to worry about (at least for HVAC and Refrigeration) More effort spent studying your specific subjects and perhaps becoming more proficient in your specialty Less chances of "this problem might as well be written in Latin" Bad Less "well rounded" exam covering fewer topics Increase in exam difficulty if all problems would follow PM difficulty (no more AM carrying the load for those did worse PM) Harder time selling old exam prep material 3 different types of ME licenses?
  12. Yeah. I brought luggage and a large backpack with me to the exam to carry around all my stuff. I too felt confident going into the exam ... at least more confident than leaving the exam. In preparation for the exam, I did a lot of sample problems, including the old school problems with partial credit and problems from the textbooks. The quick reference I used a lot for unit conversions that I didn't memorize.
  13. Folks, this is what I used to study and prepare for the exam (my exam was the October 2016 HVAC + Refrigeration exam). It might be overkill, but it worked for me.

  14. I passed the Mechanical - HVAC+Refrigeration Exam! That was not an easy exam. Wow!!!
  15. I took the HVAC + Refrigeration exam. How many questions total were you confident in?
