Hello Kumbar,
Unfortunately, each of the 180 questions in the exam has to be answered perfectly in order to earn the point that is available for it, and there are no half points. In that respect, the questions requiring dragging-and-dropping elements as well as the ones involving selecting multiple options do involve a higher risk of failure. Fortunately, there are generally only a small number of these during the exam, according to other people's feedback and my own experience a few months ago.
All the best with your preparation.
