<p>pyradax, my daughter has lower GPA than yours (although she goes to a very large test-in high school with a reputation for low grades that college admissions officers seem to know about) and no full-scale ACT or SAT scores yet (just took the ACT for the first time last week). She did start taking APs in sophomore year and since then she has gotten an incredible amount of snail mail (and nerd glasses!) from U. of Chicago, at least one mailing a week for the past year and a half. I wouldn’t use the mail as a true gauge of their interest in you. Sorry!</p>
