BU is pretty notorious for having a cattle call admissions process. Huge numbers of students apply, some using BU as a backup, and maybe half decide to go elsewhere even after being accepted at BU.
A couple years ago, they asked for "additional information" from applicants, as in another essay around Feb. 14th, BU's idea of a valentine I guess
So, no, it's not necessarily being a "good candidate" plain and simple, some pretty excellent candidates get passed over as BU figures they'll go elsewhere.
The thread is practically a SDN classic.

Can't wait to see if they do this this year. It wasn't all fun and jokes as a Peace Corps applicant who was really into BU was treated pretty poorly by some BU administrator and couldn't get help getting this additional info to the school because she was in a foreign country.
I dug up the semi-infamous quote,
"I feel as though I have shown my desire to attend BU, through my actions and through the words in my statement of purpose already provided to the committee for review.
I would be curious to know if there were any other applicants who sacrificed a weeks pay and rode for 12 hours round-trip in sweltering heat on a wooden bench seat carrying a neighbor's chicken one way in order to submit one form for Boston University."
Goes to show, that a so-called dream school can turn into a nightmare when you see what is under the surface.
