First-semester students at the University of Tübingen took the first test version of the PhaST in October 2019. As a recent study shows, the test results predict academic success in pharmacy in the first two semesters very well. The PhaST results at the beginning of the first semester correlate significantly with the grade point average that the test takers achieve in their exams in the first two semesters.
