Usually, during one of the last lectures of the course, you will be asked to fill-up a questionnaire on the organisation of the course and related stuff - it is anonymous, of course
Please, do it carefully and honestly, since it is one of the most important inputs I will have to understand what can be improved in the next year course
The fact that the course of this year is slightly different from the one held during the previous year one is mainly due to the comments I have received through these questionnaires
