I took the exam for the first time and passed! Here is some advice. STUDY STUDY STUDY. The test I took was the new test. I recommend getting the PTCB EXAM STUDY GUIDE 2017-2018. This is the newest version. Also, take all quizzes and tests you can find on the internet. They help. Narrow down to what areas you feel you need to improve. Keep studying! When you feel you are ready to take the exam, go on the PTCB website and buy the practice exam ($29). It is worth it! This is exactly what the test will FEEL like. It is timed just like the real exam. You will get your results when you are finished and this will give you a pretty good idea of how you will do on the test. If you don't do well on the practice exam, go back and study the areas you didn't do well on. Good Luck!
