When I was teaching, it was interesting to see the folks who came in without any interest in learning and just looking for an easy way to get through the classes without working. Jack might be one of those if he got that far. For one final exam in a senior engineering course, I took every other student and moved them to another room so they could not copy off their neighbors. It was impressive to see some zeros on the exam. The students had learned who to sit near so they did not have to study. > > Jack obviously never got that far in school. > >
