Believe it or not, some of the best things you can do are the simplest...get a good nights sleep, eat breakfast, get all your books, pencils, etc together the night before. I was and am a billing supervisor for an FQHC, took a boot camp and passed the exam my first time. I think I'm just a good test taker. I actually do not have to do that much coding; our providers do that. I use my certification for auditing purposes and to recognize when something is wrong, needs more, etc. I won't lie, the test is extremely hard but if you have a good monitor who will keep you aware of the time you have left I'm sure you will do fine. Some in my group did the areas they were most confident in first. I simply started at the beginning and went to the end. I did skip some questions and went back to them later as time permitted. It is very common for people to have to retake it more than once. Good luck to you and best wishes!!!
