Hey... I just took the Teas V today. The online test is VERY similiar to the actual one...It is way more involved than the book practice test. The concepts taught in the ATI book, especially science are at a much higher level of application than just the basic definitions given in the book. I studied from the kaplan book as well...I think that helped. This is a second degree for me..graduated with honors with BSED..but that was 15 years ago. I studied and studied and studied for this test..............I received an 81.3%. It is a hard test.......study and you will do well. My advice, understand the concepts....not just definitions. Ideas to study.. Periodic table and how it is organized Ion,ionic, covelant,ploar and non polar..chemical reactions and bonds..lots and lots Every part of the cell...and how it works Every detail of meiosis and mitosis All body systems and what they do The reading and grammer? Not too bad...just make sure you take your time and read carefully. Goooooooood LUUUUUCk!
