I just calculated my kid’s unweighted GPA. Looks like it was a 3.6. Weighted (school adds 0.5 for honors/AP classes, which virtually all of his were) was 4.18. I suspect that class rank was top 10%, maybe top 5%. Good suburban school district, economically and racially/ethnically diverse - about 1/3 URM, but my kid is not - white male, not first gen to college. Very strong achievement in music. Not legacy. Strong letters. ACT 36. Kid was admitted EA to Harvard this year.
So I would NOT automatically discourage someone with an UW GPA of 3.75 from applying, if they have always taken the toughest classes, and have other strong evidence of leadership, and achievement, which the OP does have.
