In principle, all in-house classes serve to discuss technical details, but also convey essential knowledge. They combine theory and practice. During the first classes students get to know each other. Thus, their ensuing cooperation by electronic media and in working groups later on is facilitated. They also learn basic techniques like working in a team, conducting a discussion or presenting a paper. Moreover, they start on the first modules. The second and third classes consolidate knowledge about the individual disciplines and selected issues as well as prepare for the internship. The fourth class is concerned with the master's thesis, too.
