Hence, students looking for courses exclusively in English must look under the section specified above for their course or under Internationals'.

Some courses also have the option of doing dissertation in German for which students need to prove their efficiency in German beforehand.

The level to be cleared is generally specified on the University website as it depends on what percentage of classes are conducted in German.
