Query: Outstanding A+ book

I used this book as a text in my A+ class, it was really good. I took the exam last week and passed both exams on the first try with good scores. I thought the hardware and operating systems descriptions were clearer than I have seen in other books and I really got the point. A couple of times my instructor said that this was the best book in the market for A+ students to use. The CD-ROM front Beachfront Quizer had a couple errors in it. Great book, thanks.
