We had a number of such requests. In all cases the reason was that these students were matched to another course for which they had a higher preference. These phenomena also occurred in situations with first-come first-served assignments, but now you don’t get students assigned who got another seat in a course which they prefer to your course. If there are doubts in specific cases, we can always check the data. The basic feedback we got is that the number of cancellations decreased compared to earlier years.
