Every semester we organize a so called prof-plenum, which promotes interchange between students and professors. In an open round, concerns, questions and problems of both sides will be addressed and discussed. There is no pressure to participate, so you may as well just join and listen.
If you cannot participate but wish for a topic to be discussed, you can send us an e-mail or throw a message in our anonymous mailbox, though, you will not receive feedback using the latter.
