It varies and depends on the school. I have an amazing gpa , 2 pubs ( one first author and the other third), 4 poster presentations, 2 oral presentations. But I can say that I have really bad GRE scores. So that is what brought my app down. I was interviewed at one program waitlisted and then rejected. I was accepted into a clinical masters program where research is not the theme. I am reapplying and retaking the GRE scores. When I interviewed there where people who did not have the level of research experience that I had but they did have amazing GRE scores, they got it. It all varies with the program and their focus. Just keep swimming, well, that is what I tell myself.
