“This year 18,124 students applied through Early Action, a 16 percent increase over last year. The admit rate for this round is 26 percent overall - 46 percent for Georgia students and 19 percent for those from out of state.
The middle 50 percent range of SAT scores was 1390-1530 out of 1600. The middle 50 percent range of the composite ACT score was 32-35 out of 36.
Beyond strong academics, the admitted students have impacted their schools, communities and families, Clark said. They’re mentors, tutors, fencers, team captains, Eagle Scouts, student body presidents and robotics champions. They range from entrepreneurs to environmentalists, from dancers to pilots and from bee keepers to app developers.
Interestingly, 47 percent of the admitted students are non-engineering majors.”

Why’s the ACT percentiles so much higher than the SAT ones?
