Assessment methods and Criteria
The official exam consists of a written and an oral part. It is mandatory to take and pass the written test before
taking the oral test. However, it is also given the opportunity to pass the exam by carrying out two written partial tests, called "prove in itinere", (usually the first of these tests is done in late November / early December, the second one in late January / early February). Who passes both these tests "prove in itinere", and accepts the proposed grade, has passed the exam for this course without other tests and the result is confirmed and registered. The partial tests "prove in itinere" consist of a written exam with exercises and open questions.
