BOOOOOOOO!!!! Not only did I waste $60 on this book, but I spent at least 5 hours of my time reading this piece of crap. I don't need to buy a book to tell me how to find the proper rate for an IV or how to calculate a concentration for a dosage form. Its called algebra. I learned it in 7th grade. Just because you add the term "pharmaceutical" doesn't mean it is any more difficult and does not mean I needed to buy the book. This book is not making me happy about being a pharmacist.
