Actually, Penn State uses test scores very little. 2/3 of Penn State’s decisions have always been GPA and class rigor. The other 1/3 is made up of all other factors, including test scores, state residency, extra curriculars, legacy, etc… So for Penn State, this isn’t that difficult to do. For other schools, like Pitt, that look at test scores more than GPA, the transition would be more difficult.
