What does your GC say? With top schools, our GC couldn't predict with any certainty, beyond letting us know that our child was in the range and whether or not she looked like a strong candidate, but with the schools that were lower on the list, safeties and matches, she was able to predict with perfect accuracy based on our school's history with those colleges, so we were sure that we had several schools to which our D would almost certainly be accepted. (Note, we had several, not one, just to be sure. The saga of Andison really influenced the way we approached the process.) I know that some schools are very unpredictable (WUStL!) while others can be predicted 100% based on numbers. Find out from your GC where Whitman falls on that spectrum, and how sure it looks for your S. If your school has a deep history with Whitman and charts acceptances/rejections, and if Whitman has been predictable up to this point, and if your son's dot on the flow chart is way, way into the range in which 100% of the applicants from your school are accepted, you can breathe a lot easier.
