grades

Any of them.
Find the girls in your sorority who are dead-set on academics and against having any fun at all. Hang out only with them. There's a subset in every group.

Everybody wants the best grades and every house has partiers and grandmas! If you want an answer id say agd but any would be good

Alpha Chi Omega. This sorority has very pretty girls who care very much about making good grades. Nickname is "Alpha Christ" b/c they are the high-achieving good girls; also known as "the house the guys go to to find marriage material." Excellent sorority to pledge, if you are lucky enough to get a bid.

Man, AXO you girls really are a piece of work. Wish I had read this before I ranked you! Anyway, every house has heavy partiers and serious students. The houses are just too big to make a house dominate in one or the other. Don't go by the gpa listed. A house full of fashion merchandising, communications majors can have a much higher gpa than a house full of nursing, pre med...majors. Ask about the hard majors, see how many girls are in the nursing program, engineering program....

There are a few sororities to stay away from. Kappa(although they are changing their rep), KD, Alpha Phi and Zeta. Otherwise, you will fit into any of the sororities. AXO is correct in their scrutiny over what kind of girls they take. Do keep in mind though just because they want girls with high stats, they aren't necessarily doing it because studying or not partying is their priority. It's about image. They have some extremely superficial and fake girls. Just beware. If you're high stats they will be all over you at rush but really make sure you know what you're getting yourself into!

I know for a fact that there are a decent number of girls who aren't drinkers/partyers in Chi O, AGD, AOPi, ADPi, DZ and Theta. Oh yeah and AXO. DG is too new and I don't know many girls from Gamma Phi but I'm sure they do as well.

alpha chi omega....they really go unnoticed.

alpha chi and alpha gam have good grades and good mix of party girls and more academic based girls. definitely the more academic based cuts

i agree with #1 comment- you will find your place/group of girls in any house that prioritize grades, and its usually pretty easy to tell in the first half of your first semester. its also good to make friends with girls in your major in your pc.
if you're looking for a more specific answer - axo, xo, agd, adpi and ddd make some of their biggest cuts first round for grades. not really sure about the others.

First, there are grade focused girls in every house, even the ones with embarrassing overall GPAs so you can find that group regardless. But if surrounding yourself with school focused girls is important you should look at a few semesters worth of grade reports and see which chapters excel in that area. Also everyone is only throwing out very competitive old row houses, and while they are known for grades it’s extremely hard to pledge there so also look into new row houses that have great grades. Off the top of my head I think #1-3 on the grade report we’re the old row houses mentioned above, but I think #4 and 5 was DG and ADPI. They were really high on the list if not those exact spots.
