ME-HVAC: I was a repeat taker so I didnt really focus on studying concepts. I felt pretty confident I knew the material. I focused mostly on practice problems.
Materials for the Test:
ME Reference Manual printed and Tabbed.
MERM
Engproguides Full Test and Reference Manual (Very Helpful)
Slay PE -
Psychrometrics and Basic HVAC System Calculations for the HVAC&R Exam
NCEES HVAC Exam (2016) and Six Min Solution.
I worked those problems 10 problems at a time. I think I went through both books probably twice.
Engproguides has 80 Questions. I focused on the areas I had difficulty.
Morning part was easy. I think I had about 1 hr left with about 2 or 3 questions I just didnt wanna be bothered with. So I guessed those, and spent the rest of the time going over, making sure I actually bubbled in the correct answer.
Afternoon was a bit challenging. But I managed to be done with an hour left. The key is to do so many problems that it becomes easy.
