If at all possible, try to spend some time practicing what they showed you 1 or 2 days after the lesson, than incorporate it into your dancing as soon as your practise gets your comfortable with it. We have always done that and the teacher initially were surprised that we know what was covered 3 weeks prior. That allowed us to get much more value out of our private lessons. teacher would just work with us on a new manuever until we understood what we were suppose to do, knowing we would do the practising to get in down on our own.
