A classmate and I went to the ACOG meeting last year in Chicago. We signed up for the CV/personal statement workshops, which gave mostly intuitive information -- nothing groundbreaking. There was another workshop that was more hands-on, but we didn't attend because it was targeted to MS-1 and 2s. It looked kind of fun though. We attended a Q&A session about the application process and life as an Ob/Gyn. The residency fair may or may not be helpful depending on where you want to apply. Some regions of the country were better represented than others. We also attended the poster presentations and Fran Drescher's speach at the opening ceremony. Anyway, the ACOG meeting is something to put on the CV or ERAS. Nobody asked me about it during interview season though. Aside from that, we did a lot of sightseeing, and I enjoyed a brief hiatus from my internal medicine rotation!
