Illustration class!

I'm looking forward to this class in some ways, and am very uncertain in others. I really enjoy hands on 2D work! But i haven't got a clue how I will perform when it comes to things like airbrush and guash (spelling) simply because I've never used those mediums before. I may find that they will be something I really enjoy! Anyway I intend to do my best and more and get an A ;)....can't wait!
