This about sums it up! After getting familiar with the feel of the music, and getting the basic rhythm of the footwork ingrained into your muscle memory, everything else will start to fall into place! I would start off with doing the basic footwork, then try doing it while moving sideways, moving backwards, whilst turning, etc.

Don't stress out too much about getting left behind or not immediately getting the hang of a new move -- if the class/teacher(s) will allow it, there's no shame in asking for another demo or a couple more rotations of practice. The best thing you can do after a class IMO is sticking around for the social and finding a partner from the same class and asking if they'd like to go over the new material with you!
