Relax. After you're sitting in front of the testing computer, there's nothing more you can do to increase your knowledge or preparation. Take a deep breath, stretch, and start reading that first question.
You don't need to rush, either. You have plenty of time to complete each question. If you're stuck on a question, give it your best guess you won't lose any points and move on. Easy and difficult questions are intermixed throughout the test in random order. Don't cheat yourself by spending too much time on a hard question early in the test, thereby depriving yourself of the time you need to answer the questions at the end of the test. Set a maximum time limit for questions, and watch your time on long or complex questions. If you hit your limit, it's time to guess and move on. Don't deprive yourself of the opportunity to see more questions by taking too long to puzzle over questions, unless you think you can figure out the answer. Otherwise, you're limiting your opportunities to pass.
That's it for pointers. Here are some questions for you to practice on. Good luck!
