is it necessary

Is it fun? Yes. Will you have a blast? Yes. Is it a great way to meet new people and have a good time? Yes. Do you have to Rush or be an outcast? No.

There are more non-Greeks than Greeks. Not all of them are walking around miserable, like zombies, because they don't have letters to wear. Just be outgoing and join activities, and you'll be fine.

That said, I'm Greek and biased, but it's a lot of fun and you should do it if you can.

I was greek but decided to quit. Not because anything was wrong with my sorority but just because I felt like I could be happier putting my time and money into other experiences. Everyone is different! You will make friends regardless.

even if you don't end up joining a sorority I would highly highly recommend you rush to at least get a feel for what greek life is all about and meet people in the process!
