I have both second edition books, and one has a 20+pg chapter on cell phones. I don't have the ability to go to an installers school right now because of work(military), so the test is the best I can do right now, but I am looking for some locally.
What type of questions do you remember if any being asked? I have a pretty sound knowledge of ohms law and how it applies. I mentioned one of my questions up above that I had and wasn't sure of.
