A sorority can help connect you with other women who have similar passions, goals, or philanthropic interests as you. Depending on the organization, they can have certain aspects of their organization which are important to them. In college I joined a sorority that celebrated diversity, academic integrity, and leadership. We would do community service, go out to different social events, and study together. One of the biggest pros is that you now have a community you can network with, which can help when you're searching for a job post-graduation. If you choose to join a sorority, be sure to do research and see which one fits your goals academically, socially, and personally.
Hope this helps!
All of the above answers are awesome! Are you interested in joining a sorority? If not, that's okay! I wasn't involved in Greek life on my campus, but I had several friends who were. They helped the community, had fun at their philanthropic events and social outings, and they had a mandatory GPA to uphold (I don't know if all sororities are like that though). Like I mentioned, I wasn't involved in Greek life and I was fine without it-- but when you do go to college it is often important to find like minded people to hang around with to help you grow and learn! My friends in their different sororities had great experiences-- just be sure to do your research if you're interested in joining one!
