Can anyone explain the 'Class of 2019' thing?

This is probably a basic question that I’m not really getting, but how on earth does one get accepted to Harvard, Yale, etc. when it’sx only 2015? And how do you even apply that early?

You start in '15 but graduate in '19. This class of '19.

@wayneandgarth Do you mean the class that’s the freshman class of '15 and graduating in '19?

@IrisShadow Yes. High school class of '15, college class of '19.

This year’s high school seniors are the Class of 2015 at their respective high schools. Assuming they graduate in 4 years they will be the Class of 2019 at their respective colleges.

Yeah, now I realize that it was simple to realize.

Thanks for the info, everyone.
