2 things:

1) This is a forum accessible to the entire world. No one knows what USC stands for. South Carolina? South California?

2) If you're asking about sororities, they really frown on open discussions of rankings and tiers on this board and in general. It's kind of considered bad form. If you're talking fraternities, it's fine to ask, but I'm not sure anyone here knows anything.

My advice would be to find out what matters to you. If you're going to a competitive southern school and you are just now asking what fraternities are best, you're already out of luck as far as getting into a top house.
