Organisation and length of courses

The academic year is divided into two semesters. The winter semester runs from 1 October to 31 March and the summer semester from 1 April to 30 September. Classes are held from mid-October to mid-February and mid-April to mid-July. Students can generally begin their studies either in the winter or the summer semester. However, there are several subjects students can begin only in the winter semester. The standard time required to finish a Bachelor's degree is principally six semesters, and a further four semesters for consecutive Master's degrees. The normal duration of PhD programmes for full-time students is 6 semesters. The overall period of study for an undergraduate degree is divided into two parts: a period of basic study, lasting at least four semesters, at the end of which students must sit a formal examination, and a period of advanced study, lasting at least two semesters, after which students take their final examinations.
