Query: Excellent with a few errors

This is worth the money but make sure this is in addition to a comprehensive study guide like Michael Meyer's A+ Certification Exam Guide. I noticed a few errors which is why I gave it 4 stars but I think it is much more of a value than the Exam Cram flash cards. I really liked the included CD. There are a 50 minutes of questions each followed by the correct answer a few seconds later. My trip back and forth to work is now actually productive!
