Once or twice every term there is a Lecture Hall Quiz in Lecture Hall G in the department of physics. Maybe you will recognize the style from a Pub Quiz. You and your friends make a team (3-5 people) and compete with others in several fields (sports, history, ….) with multiple choice and open questions. The questions are projected on a canvas and read in German and English. You can buy drinks for net cost but fun and learning are for free.
