I applied in June and was fine. When you were still on an MCAT study schedule what was your projected score? If you're just trying to go to a state school, I think you'd be fine. My state school didn't even start accepting secondaries until September and I submitted mine in October and still got an interview.
I started a new club at UGA that focused on third world medicine as well as some volunteering for the local clinic for the uninsured. I also used to tutor accounting for free when I was younger in college. Recently, I have not been involved in EC's because of the time commitment but I did help found my sorority this year and write the new charter. It's not much.
I feel like the things that I have done reflect what I want to do. Unfortunately, I have had to put myself through school and pay for a large amount of medical bills following my heart surgery last year. This summer I hope to get back to volunteering because I do love that place but working is what I have to make my priority right now.
