Presentations

There had been times on my time as a student in which I have seen some crappy presentations, this is an example. There was this one time, about a year ago, in which a teacher introduced us into taxonomy(classification). The presentation was indeed very useful, though I remember that it was like 30 slides long. Also, the slides were filled with a huge amount of words. All that info really made the subject a difficult thing to understand. The teacher knew by the 15th slide he had lost the audience. Although, she knew the presentation was too confusing, she kept on going and the next day he decided to leave us a surprise test. The test was easy, but the other 90% of the class did not think that.
