I just took the Wisconsin masters test a couple of weeks ago. The test was on Wed. and I received the results in the mail the following Monday. The test was 50 questions with a 4 hour time limit. You can bring in ANY materials that you want, no limitations. All the questions are multiple choice. It was the typical test, a couple of box fill questions, a couple conduit fill questions, about 5 motor questions, a few service demand questions based on oven loads, some haz. loc. questions, a couple of service demand questions based on lighting and recep loads, about 5 grounding/bonding questions, and a few other go find the right passage in the code questions. All in all, not that hard if you can find answers in the code book and can do the simple calculations.
