I am currently in my senior year at McGill University (I'm American), majoring in Political Science and double-minoring in Chinese Language and English Lit. My gpa is hovering just below a 3.3 right now. I am planning to submit my ACT scores to postbacs because I did well on the science section (31, 29 overall). I am wondering what my chances are at getting into NYU, Columbia, CCNY, Hunter and Harvard Extension for a postbac in premed. I know it is important to have volunteered at a hospital or with a physician to get into med school, but how important is this for getting into a postbac program? I have no experience right now and I am planning to apply to volunteer at a hospital in NYC this summer, but I will be applying to postbacs before that.
