Query: Read the book & took his class: nothing particularly insightful

I'm not a business person, but I took Mr. Ward's class and read (most of) his book. There was nothing that I found particularly insightful in here, besides the basic accounting practices that are used in the healthcare field. Good introduction, but almost no depth and the writing is not always that clear. If you need it for a class, it is not a bad book, but I wouldn't buy it just because.
