I made a 91 overall on the test with a 97 in science. I took about the equivalent of a full semester to study for it, dedicating about 10-20 hours per week. It had been about 4 years since my original A&P class and I do not have a strong science/math background, so I knew I needed to put in some serious time to do well. I reviewed each body system in depth over the course of 2-3 months, read through an introductory chemistry book, practiced math, and read the TEAS study guide from cover to cover. The chemistry book I used was Chemistry: Concepts and Problems: A Self Teaching Guide by Houk and Post. Wonderful review! For A&P I used my original text book as well as the Cliff Notes book. Also, check out the anatomy section in Khan Academy-terrific resource. For the math I bought Davis's Math Review for Nurses-worth its weight in gold. I got a 96 on the math section. For grammar, I bought Grammar Girls Ultimate Writing Guide for Students. This book helped drive home some of the concepts that I was confused about from the study guide. I got a 94 in grammar. Reading was my lowest section-81. I did buy the online practice exams, scored in the mid- 80s on both, and went through every written practice exam I could get my hands on. Do not let the online tests get the best of you- they are extremely useful in pointing you to concepts that you may need a little extra review on. They also help you know how to "think" for the test. But they can be a bit misleading. I scored upper 90s in the reading sections and 70s in the science- quite contrary to my final test results. I can say that the best review by far was the TEAS Review Manual. So much of the exam is taken directly from this book. But I can also say that I would not have done as well if I had not used other resources to really cement the concepts and fill in gaps. In the end, everything I did definitely paid off- I was accepted to all 3 schools I applied to. I was originally an art major, so if I can do it, so can anyone else. Good luck!
