Go through and understand all of the calculation examples in the back of the book. Read the code references listed in the calculations.
Some of the best advice I received about test taking was to skip a question you can't find the answer to in 30-60 seconds. Write down on a piece of paper the question number and a few words to identify the question. As you go through the exam you may come across the answer to this question while looking up the answer to another question. Then it's easy to go back to the one you didn't answer when you learn the answer.
Good luck.
Good advise,,,,,good point,,, all question are worth the same amount on the test, so basically to give yourself the best chances, go through and answer all the ones you know without researching anything first,(each one of them are just as valueable as a 10 minute calculation),,,, second go through and answer any you have to look up inthe code book and third, go through again and do all the math questions at once, so once you're in math mode, you stay in math mode,,,not go from code question, to math question, and back to code question, there's not much room in those booths, and you can't keep switching back and forth.,,,just my opinion
