Mike,

I am an electrical instructor who teaches 4 year apprentices who will be taking their exams soon. Our classes are two evenings a week for three hours. I give them 15 code questions and 15 practical/theory questions to do each class and then we go over the answers after about an hour. I ask them to pass in an answer sheet for me to correct for grading purposes, prior to going over the questions and answers. What I need, is a questions and answers book that can give me the questions I need but I want them mixed up, not all of one article or subject at a time. In other words, we use this as practice for taking the exam and getting used to looking up in the code. Unfortunately, your book is article by article. I currently use Tom Henry's book but the practical questions are not in line with what we really need. I used to use Phil Perrone's book prior to his death. Your ideas would be appreciated?
