Bass Guitar Class

My tutor was sick last Saturday,9th of January 2010, that we couldn't have class last week again. But I practiced myself what I learned last time.
Also, I've been practicing some songs, Around the world by Red Hot Chili Peppers and Hysteria by Muse. Both of the songs are pretty well known for their fast and awesome bass intro which fascinated me as well that I decided to practice. I'm now almost able to play the whole songs, but still need to make sure with the fingers and not to lose my beat while playing.
