my jazz classes

hi my jazz class was great, but it is stressing me out, I am the only person in the class so if I make a mistake the teacher will see. I can't seem to get the arms right I keep using the wrong one. Remembering the dance routine is hard plus I have nowhere to practice. The routine I am learning is from step up 2 there is a lot of walking involved. When I have learned the routine I can do it in high heels that will be fun. Got to go write an essay now speak to you soon.
