account and the student was rejected (I would think). So that wouldn't necessarily mean they don't do legacies, it might just mean that they don't make "backroom deals" to let in kids that they have already decided aren't good enough even with any legacy preference. You have to figure that BYU at least most of the time knows who the kids are and has already looked at the legacy status as a factor by the time those conversations would happen.
And it makes sense that there are limits. Harvard lets in single digits but 30% of legacies. That obviously doesn't mean a guarantee. It's more like an "affirmative action" level bump in most cases.
