Query: Worst textbook ever

I had to get this book for a project management class. It was the worst-written textbook I have ever read. It repeats itself constantly, with exercises repeating what is (poorly) explained in the body of the chapter. Constant bullet-point lists have multiple points that present (cryptically) the same point. The text is disjointedly written.Kerzner is apparently involved in the PMI testing process, and therefore a name. But this textbook was universally reviled by my fellow students. I can't recommend another book because I haven't looked further, but I _can_ urge you to find another title.
