I took the TEAS VI yesterday and I got a 92.7%! So pleased!! 91.5% Reading 96.9% Math 87.2% Science 100.0% English Language. It helped that I just finished taking A&P I and II. I also have an English degree.
I think this book is a very good resource for preparing for the test. I thought that the practice tests in this book were the most accurate reflection of the level of difficulty on the actual exam. It's the McGraw-Hill 5 Practice TEAS exams.
I also studied with the ATI book, but when I took the science portions, I only made as high as 68%. While it's still a valuable resource, I thought that the actual exam was easier than the ATI practice exams.
Just wanted to share for others that are still preparing!
