HELP!! I DON`T KNOW HOW TO GET HIS ATTENTION!

Okay.. I see that you are really scared to talk to him.. Well you need to get over that. OKay so he is in your brother class, first thing you should do is go ask your brother to talk to him and maybe invite him over your house or something and if that doesn`t work then, you step up and say something like a simple hi, how you doing, and maybe the conversation will go on farther, or you can be like wow awesome kick, great dive , stuff like that. If you really like this guy step up and talk to him. If you don`t that means that you really don`t like him!
