Most of last week was dedicated to teaching preparations and dealing with administrative requests. I had a few questions from prospective students, if they could take a particular course – if they would struggle or find it easy.It is quite clear that I cannot answer such questions – I can give advice (course content, workload, assignments,…) so that the student can make an informed decision (information that I happily provide). But if a course will be difficult or easy depends on many factors that I do not know – so without a crystal ball I cannot predict, if somebody will pass or not.
