Evaluation of courses and exams at veterinary medicine

The veterinary students have evaluated their courses and exams using two types of web based questionnaires, i.e. one for courses and one for exams by the following ascending scale:

1 = unacceptable/not at all
4 = acceptable
7 = optimal

Where the scale is two-sided, this is specified:

1 = too low/too little
4 = adequate
7 = too high/too much
