For physics major students who take his class: go to his office hour. Because the class is so easy, nobody really goes to his office hour. This is beneficial for you because if you go, you will get a lot of attention from him. He's working with plasmas, and plasma in UCLA is pretty big so talk to him about research opportunities. Even if you are a physics major thinking about switching to engineering, research is beneficial as well. Go talk to him, he's cool.
If you are not a physics major, the average score for the two midterms (about 68) is really low for pretty easy material. So I guess once you really get physics, you will do fine. If you are having trouble with homework, google it. See how other people did it. He changes numbers on the homework, but once you get it, they are all pretty easy.
Have fun!
