Hahaha, you are sweet @sunflowerlover ! It’s called the Common Data Set, lol, and you are right that demonstrated interest is more important to some schools that others.
We can honestly and sincerely get excited about all of the schools on her list. It would be great to be able for her to consider BU.
collegedata.com has full details on selection of students. BU says level of interest is Important. By contrast, BC says Not Considered. The scale is Very Important, Important, Considered, Not Considered.
One would think that a student who applied ED would have a slight advantage over RD, everything else being equal (which it never is). It’s fun to analyze and discuss this stuff but the reality is that counselors are spending 8-10 minutes on each application so it gets somewhat random pretty quickly.
