From reading this, it sounds like you only want to rush so you can confirm that all the BS you've heard about Greek life is true. Hopefully, that's not what you meant
Greek life isn't for everyone. Go to rush events and meet the guys (not just their food). If you can see yourself bonding with them, go for it. If it doesn't work out, there are plenty of other ways that you can be involved on your campus.
Good luck.
