Newbie to the board

Hello all. I am sitting the 640-821 tomorrow. I was very tempted to take one exam but after two of my coworkers ran out of time I decided to take the two exam option. I actually used the cisco intro ebook and another guide that I will not name because I am not sure if I should endorse products other than cisco on this board.

All of my experience with routers and switches is with simulation software. I will post my results tomorrow.
