I have been pulling my hair out studying for this thing... I'm using the McGraw-Hill, nursing school entrance exams study guide, and Kaplan's one. When I take the pretest in the McGraw's book, I do ok....But when I use the Kapan's book....OMG, I fail the science part. Does anyone know which book is closer to what kind of questions will be on the TEAS exam. Will it be as in-depth as Kaplan's study guide? I'm taking the exam May 7th. Any other study hints would be great!! I'm having the most issues with the math and science part. I did well in my college math classes but not being able to use a calculator is ruining me.
