I was just wondering when the Penn State Application opens for the class entering in the 2018-2019 school year?
Sept1. Everything should be in by Nov 30 so you should complete your online application (including essay and if you have a strong GPA and course rigor check Schreyer Honors College, especially if your major is Liberal Arts/Agriculture/IST/Education which have fewer applicants) by mid October in case anything needs to be sent, requesting recommendations (for Schreyer only).
is this for all campuses or just the main campus
^^ For all campuses, yes. Deadline for priority is November 30. That means everything in and complete and in their hands by November 30.
