Hi, we used the official TEAS book that you get directly from ATI at their website, plus the McGraw-Hill Nursing School Entrance Exams book. I also got her the Homework Helpers Biology book by Matthew Distefano since she hadn't had any prior science classes. For math, we used two Pre-Algebra workbooks -- one by Mary Lee Vivian, the other by Theresa Kane McKell. They were very helpful.
