Unless you’ve attended Hogwarts School of Witchcraft and Wizardry or a high school of a similar caliber, your application won’t be considered. We like to think that us muggles have a chance but we have to be honest with ourselves. Even Hermione had to be a freaking international movie actress before Brown University was willing to admit a mudblood. The Ivy Leagues have even rejected pure bloods such as all the Weasleys, except Percy of course who attended Harvard.
Dude, all I’m going to say at this point is that you shouldn’t lose hope. With your impressive resume and grades, any institution - magical (ivy) or not - would we extremely lucky to have you. Stay classy muggle!
