Poll about attendance in class

Hello,

We were rather surprised to see around 80 of you showing up for the midterm today, while there are at most 30 people in class on Wednesday mornings. Not a criticism, of course, but we would like to better understand what prevents 50 of you from coming to class. We therefore just set up a small questionnaire, which takes less than 2 minutes to answer.

Thanks in advance for your participation!

Rudiger and Olivier
