Just make sure you've eliminated any obviously wrong choices before guessing. It's also important to manage your time effectively during the exam. If you're spending too much time on a difficult question, mark it and come back to it later. It's better to answer all the questions you know and then use any remaining time to tackle the more difficult ones.
