Juniorstudy is a concept of the University of Rostock, which can be used by school students before starting their time at the University. Thus, it is an instrument of supporting the choice of study direction. Moreover, we have been able to show in our last cohort, that using Juniorstudy courses also helps to significantly enhance the knowledge required to start the university study, thus our courses become an important tool for bridging the gap between school and University. In this paper we will show the results of our study which shows that our approach improves the students' knowledge and thus facilitates being successful in testes and exams in the basic courses in the first term.
