Does Princeton send out likely letters? I know that Dartmouth and Yale do. When does Princeton announce its RD? I believe that there's a "date by" posted on the website, but have heard that the decisions are actually available online a little before then.
Also, did your HS college counsellor call to make your case to Admissions folks? My counsellor said that they won't take calls, but friends at other schools tell me that their counsellors have made a call and gotten heard.
