I had the same experiences with the other reviewers in that the review questions were occasionally inconsitent or outright wrong. The included CD mostly had tests for exams other than the A+. The book gets two stars because of its sheer volume of information, but who really cares how DOS 6.22 manages memory? I haven't had the need to use those techniques since Win95, and I haven't encountered a Windows 3.1x machine in over five years. Find another book.
