Chaz, for starters read the CCNA for dummies book. Given that you don't have any experience in the field, you'll need a basic-level explanation of the topics and terms, etc...
Once you're done, take a look at the Sybex book by Todd Lammle calledCCNA study guide. It's a fat black, red, and white book on the subject. If you can afford the personal investment, think about buying some router simulation software at http://www.routersim.com/. This will help you get practicein entering commands on a router. Actually, here's a kit of router sim software, test prep software, and the Sybex book I mentioned for $289. This should do a good job of helping you get ready.
Remember, your drive and persistence to learn this is what's going to get you through it, not a teach leading you. This will help you get a jump on the class if you're that interested in it.
Word to the Wise: Don't expect to get this certification and go out and make $45,000 like the high school is probably telling you. I've seen many schools do this and it's a shame that they think they're getting students prepared properly by doing this. There is a chance you could find a job at $12 an hour on a help desk where you won't use the CCNA hardly at all though. Just keep this in your pocket for a good night job while you're in college.
You'll also want to think of what other certifications are going to help you through college, like the Net+ and A+.
Let me re-think this... OK! Go pick up the Netowrk+ For Dummies book this summer first and complete it and the exam by the school year. Then go with my plan above, that is probably what's best for you.
