Most degree programmes at Freie Universität begin in the winter semester. Therefore, you can always apply and enrol for these degree programmes in the winter semester for the first, third and fifth semester, and in the summer semester for the second and fourth semester.
When a new degree programme starts, not all higher semesters are usually offered.

The admission regulations (in German) always state which semesters are currently offered. This information can also be found in the individual descriptions of the study programs.
