Shocked parent, advice please

From what I’ve seen on the threads for UF, FSU, and GT, I’m getting the impression that:

[ul]
[] SAT/ACT scores are being given much less weight in the applications than most people assume.
[
] The total number of AP and DE classes are less important than UW GPA and the presence of at least some of the more challenging AP courses. This makes sense to some degree since not all AP and DE classes are the same level of difficulty (e.g. AP Environmental Science vs AP Physics 1 vs AP Physics C)
[] Geographic diversity is definitely a thing and it may even hold a greater sway than ethnic, racial, and socioeconomic diversity in some cases
[
] The impact of essays will remain a mystery
[li] Universities (these three at least) are doing everything possible to maximize the use of their existing resources so that they reach as many students as possible. I’m really impressed by the guaranteed transfers, summer and spring starts, and other pathway programs that these schools have developed in order to accept more students[/li][/ul]
