Courses for beginners as well as courses for learners with previous knowledge are offered at different levels, the lower levels in several parallel groups (a, b, c, ...) due to the high demand. The courses at levels A1, A2 and B1 comprise 4 semester hours and usually take place twice a week, the courses at the higher levels only once a week (2 semester hours).
In addition, students with previous knowledge can practise speaking and taking part in conversations in a conversation course (also 2 SWS).
