I just started my Pharmacy Tech program 2 weeks ago and boy can I say this book is a tough nut to crack...even our teacher and educational director agree. This book is written as if were Doctor Speak or something. It's just one technical term after another. If your looking for something that will actually make it easier for you understand I would look elsewhere. It's good though with all the information but the way it's all jumbled up it takes forever to get your head around a few pages to understand it...especially in the cardiovascular chapter...phew!
