Resume as a sophomore?

I’ve heard my resume for rushing as a sophomore should only include things from college. I was in 3 clubs, 2 pretty actively, and have a leadership position in one of them. I also volunteered at 3 different places throughout the year. Will including all of that make the sorority think I’m too busy for them?

I don’t have a ton of awards though. I got accepted to a very selective research program and have a scholarship but that’s about it. I have good leadership and awards from a sport I played in high school as well as some community service awards from my senior year. I think they’re impressive and show what’s important to me, but should I not include that?

I realize that’s a lot of questions, but I’m really stressing because I’m a sophomore rushing at an SEC school and I guess I don’t want to be at any more of a disadvantage.
