The exam is going to take place
In previous years, the exam was "open book", i.e., you could take any material you want with you except for any electronic device that can connect to the internet. We will see this year, how this will work out in the context of the corona virus pandemic and students potentially not on site. The exam will definitely be a multiple-choice exam with about 20 to 30 questions.
