Just wanted to share some advice and recommendations, lurked here for a while and found great resources so figured I'd add mine.
Bought Dan Molloy's full course - definitely pricy but I'm 8 years post graduation, and really just wanted to be told exactly what to study and how to pass the test so I don't have to take it multiple times. I spent roughly 100 hours going through it over 3 months, first few weeks were brutal adjusting back to "academia" but he has excellent video solutions and as many practice problems as you can stomach. Came into this with roughly zero knowledge specific to exam questions.
I also bought an NCEES practice exam the week before and would HIGHLY recommend doing so even after going through all of Molloy's stuff, the look and feel is different, and I felt like it brought everything I learned from the course into the actual test.
I passed first try - test was challenging and I used up all my time. Completely guessed on maybe 5 questions, and flagged about 25 total. Walked out pretty sure I had failed if I'm honest. A few notes:
- There were AT LEAST eight questions on enthalpy wheels, both calculations and comprehension. It was really crazy, by the end I thought I was taking a heat exchanger/enthalpy wheel exam
- Zero economic analysis questions. There were two that had "cost to operate" power usage over time, but none that used the P/A tables or anything in that section
- At least 5 questions that had glycol/water solution elements to it
- The majority was heating/cooling load calcs and refrigeration cycle component knowledge ("work done by the compressor") etc
- Only one head loss due to flow (factor given), one NPSH, and zero friction/velocity/pipe calcs
If I could pass it, so can you. Feel free to DM me with questions or a discount code for Molloy's course.
