I think I would have done better at school if there had been a camera at the back of the class and ability to download the videos later. Firstly, people tend to talk a lot in class. This is distracting and makes it difficult to hear what is being said. Perhaps if there was a recoding nobody would want their rude behaviour documented. When listening to a class it is also very easy for your concentration to wander for long enough that you have trouble keeping up with the rest of the lecture because you missed something. A video trivially allows your to rewind those minutes.
