Hmmm.....
Don't know if this helps, but when I'm teaching beginners, I always say that they're never going to remember a whole routine. Pick the move you like best from the class you've done (hopefully there is a move you like in there), and make sure that you do it as often as possible in the freestyle that night. Hopefully then, it'll stick, and become part of your repertoire.
Of course, it's not the moves that are important anyhow
