Which college could I get into with my low GPA?

I feel like politely slapping you and telling you job well done through high school. Nice resume you have there! Don't be nervous because of a 3.9, apply wherever you want. a 3.9 will not bar you from ivy caliber schools despite popular belief. I myself had a 3.7 out of high school and got accepted to two ivy league caliber schools (duke and cornell). Again, job well done!
