So I've been studying for a couple months using Tom Henerys books. I am taking my test thursday, and looking for any tips that may help me. Ive never tested with PSI (the testing agency). Trying to find out what is on this test, and what the test is like is not the easiest. THey offer no practice tests. They do show what areas are tested, and how many questions in those areas. From talking to someone who took it years ago, I gathered most of it is looking in the codebook, and the ability to find answers quick. This was my main area of study, and I have become very intimate with the code book and how to find answers based on keywords in the questions, using the index. While I do have a grasp of ohms law, and various calculations. Just trying to find out what the average calculation questions are like. From PSI, they say there are 9 calc questions. Not to bad, but I dont want to afford losing them. I have taken no classes, and have earned all my hours in the field. However I feel I did put alot of effort into learning this stuff. I even studied theory throughly on my own (using Tom Henerys books), but from what I gather this isnt really tested. Ive memorized the Ohms law circle, and some other forumulas,and happen to be pretty good with math for someone who didnt go beyond high school. The other area of concern I have is the grounding/bonding there are 14 questions in that section. What are these questions like? Its a real bummer that these agencies and testing places offer no insight into these exams. I mean sure, you should know everything! But it does leave you flying blind on some of it. I really would like to pass this on my first try. When it comes to other stuff, I can find answers pretty quickly in the code book (average 1-2 mins). So anyways after all that long winded stuff.. anyone here take the Master exam in colorado with PSI? Or another state with PSI may also prove useful. Would like to know if anyone went in blind like this and passed first time. ALso.. people who didnt pass first time.. what was it that you wernt aware of that first time, that you focused on the second time. Thanks alot for any help, trying not to be anxious, but Ive put alot of time into this.. and this last couple days before the test, Im refreshing on my math before I head into this thing!
