Regarding Ph.d. applications, how important is the writing sample? I am in a top-15 Master's program right now, 3.83 GPA, but the best part of my application is my writing sample. I got a perfect grade on it from a tough grader, and I've fixed up anything that could possibly be "wrong" with it. It's definitely my best work to date. I need that because there are a couple of weaknesses in my application that I need to "make up" for, and I'm hoping the writing sample will do the trick. Thanks.
