I took the ATI TEAS VI exam yesterday for the first time and received a good score. I can honestly say that if you buy the book and the practice exams you have made a good start. However, that alone will NOT do. You MUST review the work that you already know until you are comfortable with it. This includes conversion, ratio, place value, algebra and basic geometry. Also, know the body systems, structures and functions, cell structures and functions, chemical bonding and the important macromolecules and their functions. Learn as many suffixes and prefixes as you can and go over the rules for spelling. It is not a tough exam but if you want to pass, YOU MUST PREPARE. Set aside 2 hours each day and go over a few topics. Make sure to take a break in between. GOOD LUCK!!
