You mentioned you are going to a school in the mid-west, so chances are recruitment may not be that competitive or harsh towards upperclassmen. No one can tell you here for sure unless you post your school, or the general vicinity. Anyway, here's my point with the upperclassmen rambling..
If you can stave off your desires to be in a sorority for a year, you may just want to focus on getting a feel for college life. Study hard and get involved with other activities (such as Student Government Association) to learn time-management. I did this and am going through recruitment this year and honestly, I am glad I did. While my recruitment process may be more difficult due to my location, the year I spent focusing on my studies and other activities really helped me out. I don't think I could have handled a NM period along with the classes I had to take. I'm no engineering major by any means, but I am double-majoring with a minor! I got really involved on campus and finally taught myself to be less of a procrastinator. I also got to meet a lot of sorority women from being so involved and got a better idea of what sorority life is like. So while it has been killing me to wait until formal fall recruitment this year, I'm glad I did!
Now
please don't think I'm saying you couldn't handle being a freshman and pledging a sorority, I'm sure you could!!! I know us athletes really learn a lot about prioritizing at a young age! But college is a whole new ball game and I just want you to do your best! I
love seeing women in male dominated programs, so I hope you stick with it.
Good luck at your new school and going through recruitment
