Differences between current Net+ test over previous?
So I've been putting off the Net+ for a while and have some study material just collecting dust. How much of a big difference is there between the old one and the current one? I know that with the current A+ test I just used my old study materials and demolished that test easily. Should I go out and purchase a new Net+ book to study or can I use what I have right now and be able to wing it?
