To you, there’s no point. But for a lot of kids who go into programs that have low acceptance rates (musical theater, CS, music, etc.) you have to apply to a lot of schools to be accepted to only a few. My friend going into Musical Theater applied to 30 schools with a 32 ACT (don’t know her GPA but she’s an excellent student with mostly APs) and almost a decade of leading musical roles. Only to get accepted to 7 schools. Just because you don’t need 20 schools doesn’t mean it’s the same for others.
