If you have a class, and the instructions are not given out, write them down as you do they steps. Also, if you have a camera or cell phone, take a picture of each step - that should remind you of what you did. If you are uncomfortable or can't pay attention in class to do this ( and there's no reason to be uncomfortable, you're paying for the class!) write down what you did as soon as you get home and its still fresh in your mind. I know a lot of times I'll think I'll certainly be able to remember something, but like you say, I forget too easily!
