I know many guys who rushed as sophomores instead of freshman. Naturally most rush as freshman but some people decide later they want to be in a frat-others are transfers. In the meantime he can get to know a few frats and the guys in them, He may have friends already in frats. Then he has a leg up when Rush starts. It is a drag for him but by no means does it mean he can’t become a brother in a frat. He will now have more time than most students to check each out and make an informed decision. If he knows which frats he might be interested in, he can attend their parties, etc.
