Hello everyone,

I have just registered for this forum to seek some answers. I have taken and passed the NATE core (service) exam and in order to be "NATE" certified I must take a specialty test also. I am preparing to take the exam the is closest to my own field which is commercial refrigeration (service). I am curious to find out if anyone has taken this exam and what they would recommend to study in order to pass this exam. The KATEs (knowledge areas of technician expertise) list several volumes of text books they referenced when composing the exam. However, it is not feasible for me to spend $1,000 purchasing all of these textbooks of which I would probably only reference 10% in each volume. Any information would be greatly appreciated.

Nick
