The reason I say that I agree with this book is because a majority of this book that informed of what I should do as a supervisor was what I would have already done in that situation so for me the only things I learned from this book was the technical terms for what some things were called and some laws involving ethics. this means to me that either A this book is filled with relatively common knowledge or B I would just make an awesome supervisor because my instinctual thought process gives me all the right answers. I would recommend renting this book before you make the decision of buying it. I wont be buying this book because laws and technical terms was the only thing it helped me with in that case I believe I can find a better book but if you need help deciding what to do as a supervisor then perhaps this book is meant for you.
