After leaving school, many students in Germany are not sure which discipline they should take, when they decided to study at a university. As support in this orientation phase, quite a lot of universities in Germany offer “Juniorstudy” programs. Here, students can get deeper insight into universities and into the topics they are interested in. Most of these offers are difficult for students to realize, since there are classroom sessions at the university. The University of Rostock can look back on a more than ten year long experience in offering a digital Juniorstudy program. Accompanied by advanced student mentors, they work with digital material to look deeper into their courses. By participating in presence phases, they can also get a feeling for our university. In this paper, insights from this program are sketched – both on the computer science and on the learning psychological level.
