I'm taking my exam in 6 days, so I'll update this with more insight afterward.
As far as the writing goes, this is a solid study book. The subject matter is about as dry as it gets, but author Kim Heldman manages to keep the reader awake and learning with a mix of good information, interesting anecdotes (occasionally, but would love more of those), and some humor. I was impressed as I read how entry-level-friendly this all is.
UPDATE: I passed the Project+ exam, first try, with this as my sole and only study material. I read through it once. Awesome, bumped up to 5 stars from 4.
