I got accepted to Vanderbilt, University of Washington, Northwestern, and UT Dallas. I have a 3.92 overall GPA and somewhere around there for major GPA too. I got a 1330 on the GRE (620 V, 710 Q), and I only have scattered work experience and basically no volunteer experience. My mom is an audiologist and I have worked and observed at her clinic, though. I also got three letters of recommendation that included the head of the department of speech and hearing from my undergrad at UW. I do think that GPA and GRE matter quite a bit.
