I have never encountered a set of books this well done. Everything in each book is written to help you understand the CompTIA A+ certification. It addresses the topics with a great overview and then specifics. It starts with a test to establish your level of experience. It is written in a way that lends itself to moving around to different topics to keep things fresh. There are online flash cards aplenty! There are also a ton of practice questions both in the books and online. These books increased my confidence, not just because the exams helped me learn that I knew more than I thought, but because I feel confident that I can learn the rest! Thank you for the great job!
