I did my masters degree at Sorbonne University and was lucky that there were only around 20-40 students per course. The majority of professors are excellent in their field and provide passionate classes. I only regret that the teaching style is rather old-school in most classes with professors giving lectures with not many possibilities to participate. I would have preferred to get some documentation other than my own notes in class, as you only concentrate on taking a maximum of notes, but you can’t really pay attention to the content of the lecture itself. Moreover, the equipment of the university is pretty rudimentary in terms of projecting presentations etc. However, I really enjoyed studying at Sorbonne and the quality of the classes definitely made up for the downsides.
