I knew it

So I convinced Josh to take some harder classes. He came home the first day and said "Mom I have got to trade out of a class!" So I said what class? He said" Honors Physics!! I don't know anything about it." So I said well just try it out and then if you have issues we will get you out of it.
TODAY at the Dr. office, he said " Guess who was the first one done on a test today in physics, and guess who knew all the answers?" I looked at him with big eyes. He said "everyone asked me how I knew it, and I said I don't know I just did."
I hope he gets it, and I hope he does good in it.
