Is there a minimum GPA for the different organizations?
There is no GPA requirement to go through the Formal Recruitment process, but some groups have strict GPA requirements of their own. You are encouraged to ask this question during the Formal recruitment rounds.
NPC affiliated sororities have between a 2.6 and 3.0 high school GPA threshold for top consideration. If you have a lower GPA than this, it is important to remember that there are some exceptions and this is not the only factor.
NPHC groups have between a 2.5 and 2.6 minimum grade point average from Ole Miss to pledge and actives must maintain a minimum GPA of at least a
2.4.
IFC affiliated fraternities have no minimum high school GPA to join but they do have a minimum 2.0 grade point average to be initiated. Many fraternities, though, have higher minimum GPAs for initiation. To find out what the minimum are, ask one of the members during Formal Recruitment Week.

Read that too...that's about the sorority's requirement...basically if you don't have a 2.5 you need to have a doctor's note...This new requirement has deterred some girls from going through and getting their grades up their first year of college to go through their sophomore year, but not that many...
