If it is U of Michigan you are talking about, I think good board score is not enough, I think you also need to have a very high class rank. I don't think GRE score is that important. I had 96 part I and almost 2000 GRE score, but not interview from U of Michigan when I applied.....my class rank wasn't in top 10...that is why I think high class rank is very important for Michigan (and most other program as well).
