S.P. Lopez, former UP President on “terror professors”: “who habitually flunk a large percentage of the students in their classes, causing an inexcusable waste of University resources. I pointed out that when more than half of the students in a class flunk the course, it is not necessarily because students are dumb; it could be because the professor is incompetent. Good teachers, I said, are not born but made, and a Ph.D. degree does not guarantee that a professor knows how to teach.
