Yes, it is a great opportunity! There is a category on the AMCAS primary application for presentations. I did a poster presentation and a couple of oral research presentations at different conferences. I talked about how I enjoyed sharing my research with others and how my presentation ability improved. My first interview they asked me about my research presentations and if I would continue with research. Did you apply this cycle? If you did you could always send an update on this experience to schools. 🙂
