I took Cisco 1-4 in highschool but thanks to our teacher not caring and giving us his admin login to get the answers, us passing=him getting paid....so I didn't learn anything because I took an easy grade.

Anyways, I am going to start working on getting some certs, and figured I would start off with A+ and Network+ before going for a CCNA and etc, I am currently working an IT helpdesk job doing tech support for colleges, but onto the reason of this thread.
In my Cisco/computer class I got a Michael Meyers A+ book, and I seen the same book in the recommended study books, but it showed Fourth edition, this book is from 03/04 that I have and it is the 5th edition. If I read all of it and etc I should be able to pass and get my A+ fine right?
It is the All in one 5th edition, and I see there is a 6th edition out.
