I used to wait until I had learned a move twice in two different classes, as after one lesson I usually found it too difficult to try and freestyle it. After learning it the second time at a second class I would try and dance that move once or twice to every song that night at freestyle. With luck it would become part of my repertoire.
As I learned more moves I found I could usually look around and be reminded of moves I'd learned in the past because other people were doing them.
In competitions I've often relied on my partners giving me a verbal lead (do 'x' move now) because when you're nervous your memory just tends to go out the window. It doesn't sound very professional, but who can tell
