On the KKG national website, it states that PNMs must have "a C+ average from the previous completed term at a college or university, [and] many chapters have academic requirements that are higher than the Fraternity’s." To be honest, I don't know exactly what our chapter requires. Without giving away info on MSS, I'll just say PNMs' grades are treated as a very private matter between the Membership Chair and the advisors. Since recruitment is deferred freshmen have a full semester of college under their belt, but Hopkins has a "covered grades" policy in which your first semester grades are all considered pass/fail (though the GPA eventually factors into your cumulative). I think PNMs sign something so that their grades can be "uncovered" for recruitment. In any case, Hopkins has absolutely ZERO grade inflation and it's easy to get overwhelmed first semester, so I would guess chapters are a little more lenient than they might be elsewhere. A lot of freshmen go from getting straight As in high school to something a little... harsher.
