I think you are certainly in the ballpark if your SSAT come in as expected. Your UW GPA is really what matters - the prep school will be interested in seeing that you pursued rigor.

If you are dead set on attending BS, you should expand your list to include some other schools that are equally excellent but somewhat less well known (and hence less competitive.)
