CCNA Docs?

Hi just started a CCNA collage course does anyone of good sites with some documentation I can print out to use?

I have done one of those and from what I remember you get loads of online material to work through as part of the course.

At the moment they are just giving out the history of Cisco and the hole networking side of it but its boring and most of this stuff I have done I’m really just looking for something I my self can be looking over while everyone else is still stuck on the basics.
