Looks like I had the opposite experience. I didn't do as well as I thought I would on the verbal and quantitative (650 and 740 respectively), and I did slightly better on the AW than I thought I would (6.0). I have a typical philosophy resume--3.98 GPA, heavy philosophical courseload, very analytic undergrad department (UVA).
I suggested improvements to the argument in the critique part of the AW part, and I referenced Alasdair MacIntyre and Aristotle in the prompt. I didn't think I did anything special.
