"I had one experience which gave me some slant on the way large organizations run. I was not allowed to take spherical trigonometry because I'd sprained my ankle. Because I'd sprained my ankle I had an incomplete in gym, phys ed. And the rule was that if you had an incomplete in anything, you were not allowed to take an overload. I argued with some clerical person in the administration office, and was stopped there. It's an experience which I've remembered since, and advised people not to be stopped at the first point."
