Seriously.. talk about geographic diversity!
When you say you "come from a first generation college student" are you talking about yourself or did your parent (who you came from) graduate college? If it's the former, I think that's helpful. If it's the latter, not so much.
Have no clue how large your school is, but five accepted a year is a pretty good stat to have on your side. Son is current freshman and did not end up in the top 10% (although I would guess he was pretty darn close), however he did take the hardest curriculum his HS offered, and did very well.
As for scattergrams, of all the schools son applied to, Middlebury was the most all over the map in terms of acceptance and even more so than some of the Ivy's where you could visually see who the athletes or other seriously hooked applicants were. As it is, some of the "smartest" kids who applied to Midd haven't gotten in, but scattergrams only take into account standardized test scores and grades and say nothing about student character (reflected in essays and recommendations). While no one can really say what goes on in admission offices, you'll never know unless you actually apply.
