Chris from Chris’ Blog put has a great post on teaching others to help you learn. This is a great idea. I try to explain to my wife all that I learned in class on the way back. I figure if I can explain proximate cause or the parol evidence rule in a way that she can understand it, then that means I have a pretty good grasp of the material.
Another thing that I do is review my outline each week out loud like I were giving a lecture. I shut the door and start jabbering away. This seems to have helped as well.
