According to the Auburn sorority recruitment website:
You will need to know your final high school GPA for your registration. We ask that you report it on a 4.0 scale. Weighting for honors and AP classes is allowed. So, get that ready before you begin.
This appeared on the page that you see when you click to register for recruitment. Be sure to read the website thoroughly, there's lots of good advice there. Good luck!
