“Test scores” being the only Academic factor they downgraded to Considered might be trying to communicate something.
I do think Brown, among other things, is trying to impress on potential applicants that they are very serious about your HS transcript, including grades, rigor, and all that, notwithstanding what they then do with their own curriculum and evaluation plans. Although again, people who really know Brown understand that is less of a contradiction than some might assume–like, open curriculum really doesn’t mean anything goes, that there are ways ambitious Brown students distinguish themselves, and so on.
