It's a great book for its purpose, being a business primer. I looked at it as a very detailed complete MBA syllabus. This touches upon the basics that you are going to learn in business school, but of course, you will dive further in school. However, if you want to prepare yourself a bit for what you're in for, or if you're not sure that an MBA is for you, this would be a great book to read to answer that question. I'm about to start an MBA program with no business undergrad experience, and after reading this, I feel much more confident that while I don't have any educational experience in business, my professional experience has given me a better understanding of the business world than I thought.
