Last year I applied to just Yale and got rejected. This year I applies to Yale, OSU, Vanderbilt, Seattle, Columbia, Minnesota, and Oregon and was accepted to Yale, Columbia, and OSU and waitlisted at Vanderbilt. Don't give up on, waitlists move fast as folks choose schools and even if you don't get in, you'll be a better candidate next year. I was devestated and had a stressful year of more courses and volunteering, but it was definitely worth to stick it out and apply again and I feel way better prepared this year.
