Hi,
YES...it takes time, but most of it's fun. I really enjoyed my DZ experience in college. The time it takes is worth it, and honestly, it won't seem like much because the sisters will become your friends and when was hanging out with your friends something you checked your watch while doing?
As a new member, you will be learning a lot about the sorority, the chapter, your new member class sisters, working on philanthropy projects, coordinating various activities, etc. You will also be expected to keep up your grades, be well rounded with perhaps a job or another student activity, be the best co-ed you can be (ie: don't embarrass the sorority), and look cute while doing it (JUST KIDDING!).
The benefits are great leadership possibilities, wonderful social opportunites, life skills that will help you in the future, and friends that you will take with you after college.
My favorite thing about DZ is the sisters that I have met AFTER college. My alumnae life is wonderful. My alumnae chapter(s) sisters are my best friends. I never imagined it, but it's turned out that way. Delta Zeta is for life!!
Good luck!!
