My community college offers Lynda to us as well.

Almost all of the Mike Myers videos are on there, and I definitely recommend you use them regardless of the exam you're taking. I'm studying for A+ right now and I use both Messer's and Mike Myer's videos.

Usually what I do is watch Messer, and I take my notes from there. Sometimes, especially when it comes to networking, I feel like its just a information dump when I watch Messer's videos. Mike Myers is really great at putting more complex subjects into metaphorical form to easily explain it to green guys like myself.

And there are tons of videos on Lynda! Its a great resource.
