Dear bluebayou : Thank you very much for the tip-of-the-cap on the "Why BC?" discussions.
Dear hellUVAchance : First, let me say that the embedded UVA reference scores points on creativity. Second, let's spend a few minutes thinking about your letter of continued interest.
If you are seriously dedicated to the admission's cause and want to demonstrate your passion, would you write a letter that has a salutation of "Dear Sir" or "To Whom It May Concern"? Of course not.
So, why would you send a volley over the net to the "Admissions Committee"? Your opening step should be to contact admissions via telephone and find out who the reader was for your area (state). Your second step is then to call that person directly, introduce yourself, and have a "cheat sheet" of the top three elements that you bring to the Boston College campus that might not have been previously accentuated in your application. Have those points well rehearsed - what leadership skills have you been honing? How is your senior year rigor and grading? What are you doing to prepare yourself for college and specifically BC?
Only once these are done should you send your letter of continued interest - but now, you will have additional concrete elements in hand to reference in your follow-up letter.
In the new computer generation, many exchanges take place in a very antiseptic manner; by this, we mean impersonal. Now is the time to make yourself known as a key asset for the Boston College campus and there is no better way to start that process than with a phone call and then with a letter ... or even an actual visit to the campus if feasible.
Hopefully, you find this advice useful.
