I’m a male student in a fraternity and I am very happy with my experience. I have a number of female friends who are in sororities and they are very happy with their experience. If you PM me I could give you their contact information or answer any questions you have.
Also, while membership dues are high among some sororities (especially the Panhellenic ones) they vary in their amounts as do fraternities.
Many students at the U of A have negative opinions about Greek life, but while some stereotypes are true for some organizations, there is a fit somewhere for nearly anyone wants to join!
I hope you find your experience with Greek life as rewarding as I found mine!
