Just by playing the game naturally will give you some skills. Once or twice I got called upon to be a judge before I passed the exam when there was no Professor available. Studying the Compendium, Penalty Guidelines, and Rulebook is your best bet. You may also want to read up on Tournament Rules and Procedures. Make sure you know that the test is timed. If you pass, once you submit the test it will state which questions, if any, you got wrong and the correct answer. If you did not pass, it will list the questions you got wrong, but it will not provide the correct answer.~Mark
