I studied the McGraw Hill Book. It helped to get me familiarized with the Reading and English portion. However the test questions on those areas are a lot more difficult and intricate. The Science I had on my test was mostly Chemistry and Physics which is a huge bummer since you don't need either for an ADN program. You don't need physics until a MSN program if at all. So, that was a huge shocker. The math was just basic algebra. I wish I would have had the ATI manual. But, I have heard that the ATI doesn't prepare you enough for the Science either. I feel like the Science is a very important part. If they had actually tested me on Anatomy, Physio, and Micro I would have done amazing on Science. I had 1 anatomy question.
