I promise some kids have. My daughters school it all boils down to freshmen year. Some kids had 1 extra honors choice and others opt for a summer class for DC it truly is a COMPLETE GAME!
She is like your son gpa wise (3.78UW 31 ACT sophomore), but is ranked barely top 20%. Some kids have 3.98 gpas.
She is smart and we dont care about top 30 schools, Im not forcing her to jump through a million hoops to be competitive with this fanatical people. Taking summer classes to bump gpas is more than I think a student should have to do.
Your son will be fine as well.
