I was fortunate enough to find this site fairly early in my studies. I'm proud to say that I passed Thermal Fluids on my first attempt through self-study, largely thanks to the guidance of those on this forum. I wrote up a study guide for a buddy that's taking the exam, but then I realized that I should probably pay it forward a bit here. So without further ado, one engineer's opinion:
Mechanical (Thermal Fluids) Study Guide:
Before you begin—some required reading / viewing:
This thread. You're here already. Congratulations!
Youtube ‘Dr. Tom ME PE exam strategy’. He has several videos about test taking strategy. He lays out how to map out your study plan according to how many points are in each subject. A great strategy.
Read Lindeburg’s ‘Introducton’ section in the MERM. It is a fairly comprehensive overview of the PE process and is filled with helpful reminders and tricks. It helped me frame the way I studied to better mirror test conditions.
Study time & commitments:
I started studying in early January for the Apr-15 test. I wasted a bunch of time early on reading through the MERM in the hopes of shaking off the rust, and forgot quite a bit. My recommendation would be to start 12 weeks ahead of time, and to take a few days of vacation time in the two weeks prior to the test. There’s a lot of material to master—if you study for over three months, you’ll start to forget things.
Study Materials:
You’ll need to acquire the materials that you’ll use during the actual test. ‘Practice how you play’. The Lindeburg MERM has a pretty good list of potential items. I’d recommend the following:
- · MERM
- · Lindeburg Units Conversion book (in a 3 ring binder or as a standalone book)
- · Random notes binder (2 page study sheet and other small items)
- · Steam tables (I cannot stress how important this is)
o It should have saturation and superheated tables (by both pressure and temp) that go to at least 5000psi. Also, it should have the metric equivalent to US.
- · 11 x 17 psychrometric chart (this will be 3 ring bound during the test, but loose is fine for studying)
o You should have a ruler for this, as well
- · Air tables (similar format as steam tables—obviously without saturation data)
- · Calculator. Make sure it fits the NCEES requirements before you start studying.
- · Kitchen timer for timed sessions. Avoid the temptation to use your phone—you won’t have it on test day.
For problem sets, you’ll need:
- · The 2001 NCEES test
- · The 2008 NCEES test
- · The Lindeburg practice exam
- · Lindeburg’s Practice Problems
Some of these exams are difficult to come by. I’d recommend that folks check with their library (especially if you have an access to a University library system). I was able to find a few books on location and successfully transferred a few more through an inter-library loan system.
The Tao of the PE study plan:
Rule 1: Know thyself. What type of learner are you? Is working problems only on the weekends good for you? Would you benefit from a review of some of the theory (there are ME undergrad lectures available all over youtube, if that’s your bag)? Do you need to be out of the house to avoid distractions?
Rule 2: (T)CREAM-- . Test Conditions Rule Everything Around Me. You are attempting to pass a test with very specific parameters within a finite amount of study time. Your studying should reflect that. It’s easy to get into the trap of trying to read through theory or work very involved practice problems (ie some of Lindeburg problems). Focus on the goal. How are you going to solve problems at a 6 min/problem clip with over 75% accuracy? How have you prepared for the mental marathon of an eight hour exam under these timed conditions?
Practical study outline (12 weeks):
- · Week 1: NCEES 2001 afternoon test under untimed conditions
- · Week 2: NCEES 2008 afternoon test under untimed conditions
- · Week 3: NCEES 2001 afternoon test under timed conditions
- · Week 4: NCEES 2008 afternoon test under timed conditions
- · Week 5: NCEES 2001 morning test under untimed conditions
- · Week 6: NCEES 2008 morning test under untimed conditions
- · Week 7: Lindeburg afternoon practice exam under untimed conditions
- · Week 8: Lindeburg morning practice exam under untimed conditions
- · Week 9: Work through core topics and areas of weakness
o Your focus should be 80% afternoon and 20% morning session material.
o Use Lindeberg practice problems and MERM chapter problems to supplement
- · Week 10: NCEES 2001 afternoon test under timed conditions
- · Week 11: NCEES 2008 afternoon test under timed conditions
o Review / scan the three exams. Walk through how to solve the problem. Note any areas still giving you trouble.
o Generate study plan for next week based upon areas of weakness.
o Double check documents and materials needed for test
- · Week 12: Study light, organize materials, and get some rest
The schedule above is rooted in a couple of personal observations:
- · Reviewing old college materials (textbooks, notes, etc.) or the MERM itself is not terribly efficient. Getting reps in on the NCEES exams is good practice for the actual exam, while also exposing you to the theory.
- · The NCEES exams are a good way to work your way up to more difficult problems, while also exposing your areas of weakness.
- · A fair amount of Lindeburg’s materials (Practice problems, MERM chapter problems and the practice exam) are an order of magnitude more complex than the NCEES exams and what you’ll encounter on test day. However, they are vital in ensuring you have a greater breadth and depth of knowledge.
o The NCEES exams represent snapshots of how they might compile an exam. They can (and will) change which topics they emphasize, and introduce content that is not present in either the 2001 or 2008 practice exams.
- · There is nothing like a test under timed conditions to teach you the intangibles of test day, and to guide your study habits.
An Ode to Cheat Sheets:
One of the materials I used the most on the test was a cheat sheet. It was two pages of the most commonly referenced equations I encountered in studying the three exams. It also included where the equation / topic was found in the MERM (i.e. 36-7) in case I needed to flip to it for context or similar equations.
I recommend a cheat sheet two main reasons: (1) It prevents a ton of flipping through the MERM, which costs time; (2) Compiling and writing a cheat sheet is a form of study. When you have to write out the equations, you’re forced to look at its components and to understand why a solution calls for it. Some also may argue that connecting content to multiple senses / experiences helps retention.
How to compile a cheat sheet: After you complete an untimed exam, compare your solutions to the book’s. At the same time, try to identify which equations they used. Locate the chapter and page number and write it down in the margins of your scratch work. After you’re all done, march through your scratch work and type up the equation and chp/pg number in a Word Doc. Try to group ‘like’ topics together as you go.
The next time you take the exam (timed or otherwise) use your cheat sheet. It’ll dramatically reduce your ‘flip’ time.
The Art of the Timed Practice Exam:
I found timed exams to be the most valuable form of study. I recommend doing a four hour test on Saturday, scoring it in the afternoon and then working through deficiencies on Sunday / the following week. It makes for a decent weekly cycle. I didn’t do eight hour mock exams, because I wanted to be able to reflect on all the content and immediately rework the problems. I feel like I had enough endurance built up for the real deal, despite only doing four hour exams.
Set yourself up at a table with a 4’ x 4’ work space. Why 4’x4’? That’s the space we were given on test day—it was a bit awkward, because it’s a bit harder to reach materials way out in front of you.
Get your kitchen timer ready and be sure to keep any drinks or snacks on the floor.
Some things to think about when you simulate the test:
o How do you deal with skipping / ranking problems? I found that ranking them by difficulty was a waste of 10 minutes and that working them in order, reading them thoroughly and then evaluating whether to skip them was more efficient. I’d then write down the problems I skipped on the final page of the test booklet. By the time of the actual test, you’ll be experienced enough to know the difference between a three minute and an eight minute problem by reading it.
o How much time are you spending on each of the problems? I found it helpful to write down how much time I spent on them in the margin so I could review that info afterwards. Obviously, that’s not something you need to do on the actual test.
o Did you notice that you were missing any materials that you needed to solve the problem? Which resources did you use the most? Are there any opportunities to cut down on flipping between the MERM?
o How’d you handle the mental fatigue? Eventually, your brain will become more accustomed to running marathons.
o How much time did you have left when you worked through the test? How many problems did you need to come back to? For example, you may have gotten through all the easy ones with 45 minutes to spare, and had six hard problems to come back to.
o Were you scrambling for time at the end? How many did you guess on?
o How many fluids did you drink? How many times did you need to get up to go to the bathroom?
Mark up your test and note the results. The metrics I used to track improvement were: score (duh), how fast I completed my first pass, and how many problems I needed to come back to. After a while, you’ll also be able to mentally handicap what your score will be based upon those the latter two metrics.
Work your way down the ‘things to think about when you simulate the test’ list two paragraphs up. How can you cut your time or improve in any of these areas? I saved a bunch of time flipping once I switched from MERM steam tables to a separate flip book, likewise with having a cheat sheet vs. looking up things in the glossary. Adjust your future studying accordingly.
Breadth and Depth:
I mentioned it earlier, but the NCEES tests alone are not enough to prepare you for the exam. You’ll need to crack open some of Lindeburg’s materials to get a sufficient body of knowledge.
Lindeburg is kind of like that one Professor you had that makes things harder than they should be in real life. There is a method to his madness—his problems require that you draw from 2 to 4 pieces of theory and many conversions/calcs, whereas the NCEES only requires 1-2 pieces of info and fewer conversions/calcs. By hitting Lindeberg’s material later in your studies, you’ll have a base knowledge before running into the buzz saw.
The study plan outline devotes weeks 7 & 8 to his exam. It will take 2 or 3 times of walking through the exams to understand how he attacks the problems, or to gain an understanding of the new concepts he introduces. But you’ll be glad you did—working these problems netted me a few extra points on test day.
Week 9 is devoted to introducing supplemental material. To date, you’ve only worked 240 problems, some of which were essentially duplicates. By now, you should know which areas you’re weak in (take a look at the three afternoon exams for inspiration). Figure out which MERM chapters make the most sense to target. Work all sample problems in those MERM chapters (usually 3-5 a chapter) and work a couple of the companion MERM practice problems. Shoot for about 30-40 extra problems that week-- do more if you can.
Finish Strong:
The last couple of weeks should be heavily focused on afternoon topics, getting timed test reps, and addressing deficiencies. Two weeks out from test day, you should have a good base of knowledge, a fairly complete cheat sheet, and be getting passing test scores under timed conditions. Still, there will be lingering doubts about certain topics, and whether or not you’re prepared.
If you can, take off from work on the Friday before the exam, and the day before the exam. Your week before the exam should look like this:
- · Thursday night (-8): Scan the three exams and put together a study sheet for the next week. Work problems / address deficiencies (3- 4 hours total).
- · Friday (-7): All day working problems / addressing deficiencies
- · Saturday (-6): Work a timed NCEES afternoon exam. Score it that afternoon and work the problems you messed up on. Keep working through any deficiencies.
- · Sunday (-5): Take a look at the break down of problems for the morning session—what’s your level of comfort with them? With all the emphasis on afternoon session materials, you could miss an opportunity for easy points (i.e. beam bending, econ, manufacturing concepts). Cram for anything else you might have (morning or afternoon) and finalize your cheat sheet.
- · Monday & Tuesday (-4 & -3): Lightly review any remaining items. 9 hours of sleep
- · Wednesday night (-2): Read through Lindeburg’s ‘Introduction’ section in the MERM and note any outstanding issues (triple check your paperwork). Organize all of your materials and then kiss them good bye for 24 hours. 9 hours of sleep (make sure to go to sleep at a time that simulates test day)
- · Thursday (-1): Wake up like you’re going to go to the test. Simulate everything until you’re ready to hit the door. Then relax-- it’s a ‘You’ day. Blow off some steam, loaf a bit, hang out with the family, or whatever floats your boat. The one piece of ‘work’ I did do was to drive by the test location to make sure I knew where it was. 9 hours of sleep.
Test Day:
Nail it, and then, as one of my Professors used to say, ‘Go pound some Budweisers’.
Good luck!
