The part where I struggled was the HVAC depth section. I feel that the MERM is lacking in this area. Does anyone have any suggestions on other helpful study materials? I purchased the HVAC 6 minute solutions book and am looking for others as well.
I actually was just about to buy the other 2 SMS books (Machine, fluid) but the reviews on Amazon were really bad (unlike the HVAC SMS reviews). Considering only the breadth questions in the SMS will really help me for am section, I'll wait and see if i spend $ 50 for 20 questions. the reviews also stated the solutions are wrong. Not sure if anyone else has experience with that. but i think as long as i skip questions int he "500" questions book, I might as well save the money.
not sure yet, but I'll exhaust all other study material first.
