Notification is by snail mail. Admission to Honors/Scholars/FIRE (or other LLPs) or a LEP is not an indicator of merit money. There are some things that have changed with admission this year, so what was previously unpredictable, is even less so now. I can only tell you that in the past, it seemed that merit money was casually related more to standardized test scores than to gpa, but of course, that was only an opinion, and not based on any fact.
