@megabee Hi! The fact that you got into Michigan straight from undergrad goes to show how successful you are in this application cycle.
I was intrigued by your point about research experience. If I can be blunt, your published paper and conference presentations don't stand out to me. Many people in my MA program have national conference presentations (APSA, MPSA, ISA) or multiple of them. I'm not sure how much "research experience" did in getting us into Michigan. Could you share a little of your thoughts on what got you into Michigan?
(I could be 100% wrong and that research experience is the most important thing but until proven wrong I don't want to give perspective applicants the false impression that they can flood undergrad journals and conferences and not put as much effort in other aspects of their application)
