I took TCP/IP (graduate level) when I was studying for CIS degree. I have mainly focused on programming, including database stuff so far. My hands on networking experience is basically, setting up home wireless network. I know some Linux, not administrative level yet. I checked CompTia's site for their certs exam to see which book/ material to get. I want to stay general at this point. Any recommendation what approach I should take w/o costing me a fortune to join schools like ITT. After all, I can stuff on my own. Just need the right material to choose from tons of stuff out there.
