Presentations were important because the marks for them affected your degree level. Despite dire warnings on time limits, these were handled casually. Favourite students were allowed to overrun the 20-minute "limit". Others were cut short. My presentation was cancelled twice because of lecturers' illness but rescheduled at short notice - in one case with no notice. The lecturer became hysterical when I pointed out the problem. Also, despite emphasis on the importance of hand-in dates for essays, the corresponding obligation on lecturers to return marked work before the next assignment was often ignored.
In a company, such inefficiency would be intolerable. The only saving grace is what one learns, and the friendliness and respect one encounters on the course.
