How do I tell my parents I want to join?

[ohhai]

My parents are the ones who will be paying so I do have to ask for their permission.

And I am worried about my GPA not being high enough

Just tell them that you're interested in Greek life and you think having something to be part of would give you additional incentive to do well and stay in school.

Be advised that if the two schools are very different, Greek life will be also. Check it out, but don't automatically think it will be like it was at your first school.
