Passed on second try...What did you do differently that allowed you to pass this go around?
This is good info. It's important to be able to break down a question and understand what they are really wanting you to do, because it's not uncommon for them to give you a bunch of information that has zero relevance to the question being asked. My mistake the first time was knowing how to solve the practice problems but not understanding the concept as to why it was solved that way. It's important to know how to work a problem, but also consider what other questions they could ask from that same problem if they were to give you other pieces of information. Take a cycle for instance (I took Mech. Thermal & Fluids). First time around I only knew how to solve for what the practice problem asked, and even then I had to look up the equations. Second time I knew the concept of how to solve for heat in, heat out, work in, work out, etc and had done enough examples that I was confident in my knowledge of the concept to the point that I didn't have to look anything up. Given infinite time I could have passed the first time, but I was terribly inefficient due to my lack of conceptual understanding.The test, tests a lot more than just knowing the material. It expects for one to figure out what is really being asked. To me, that's always been dumb. But of it weren't that way, phycometricians, wouldn't have a job.
The last paragraph. Read it carefully! That's why I passed.I'd recommend a review course such as GT or School of PE. I think both are good. The Graffeo book is an excellent resource for the exam. There is some good information inside and I would tab all of the tables, charts, etc. Work EVERY PROBLEM in that book including the examples and the practice tests in the back. The Graffeo book doesn't do any amount of training for the NEC/NESC but grab a book and the NCEES practice exam to get an idea along with the Complex Imaginary code book and practice exams. I went through the entire graffeo book including the practice exams before the 6 week online course started and that was a big help. The online course moves fast and there is homework issued. I would have been lost if I hadn't already put in lots of time studying.
About calculators....
I brought two to the exam, an HP35s (primary) and a Casio fx-115ES (backup) along with a new set of spare batteries. I used an HP scientific through my engineering courses at Uni (HP33S) so I had a lot of exposure to doing calculations with my HP. The best thing about the HP35S is that it has a robust algebraic solver and the ability to store formulas. This is great for doing relatively straightforward calculations that can be error prone (like calculating the +, - and zero sequence currents). One of the best features of the Casio fx-115ES is the excellent complex number menu it has that allows for rapid conversions between rectangular and polar formats. You can even enter polar and rectangular numbers as part of a calculation (and the display looks exactly like what you have on your paper) which is sweet.
The best advice I can give on exam day is bring your own lunch (don't leave the test location property) and don't get flustered. Keep calm, cool and collected. The minute you start thinking you've lost the battle close your eyes, look at the pretty woman across the room, think of how that beer will taste later tonight when you're out of the exam. Find something to escape to for 10 seconds then open your eyes, re-read that problem slowly and attack it. No amount of studying for this test will help more than the ability to not give up and to keep going when you first read that problem and panic because you have no clue how to solve it.
