If you have the money (around $300) I would definitely recommend going to Testout.com. The training cd’s that are offered are unbelievable. I bought their CompTIA suite on special and I’m now A+, Network+, Server+, and Security+ certified and I’m working on my Linux+. And this is the ONLY training I used. No books, just the software provided by Testout.com. Its a really deep training experience with instructor-led teaching sessions,a virtual hands-on workbench, great notes and hundreds of practice questions. It really helps you understand and use the technology rather than just being able to pass a test.
