Late arrival is no problem; you can join classes any time. In the worst case, you will lose this semester and you will commence your studies
next semester. However, please note that your examination deadlines will not be
interrupted by this; your obligations associated with your studies will remain
unaffected.
The standard period of study for a master
program is 3+2 semesters. All examinations must have been taken for the first
time by the end of the 5th semester. Otherwise, they are automatically assessed
as "failed" (incl. the Master's thesis). For the Master's thesis
there is then one further attempt, for all other examinations you have 2
further attempts, i. e. the program is not limited to five semesters.
