I know sometimes folks skip answer videos after quizzes when they got them right on the first try. In general, you should make sure to watch the answer videos, because they sometimes have extra content in them. For example, in unit 2-28, there is an interesting digression into the history of computing. |

Good point! The answer videos have a lot of information in them!
Very true - I learned a lot about how the instructors think from seeing how they solved the problems in the quizzes - this helped me anticipate the approaches they were looking for in the homework (test other values for the variables, test other values for the variables became my mantra, but only because of how the instructor delivered the answer videos.)
@pamela Indeed - and beware positive bias. Which values should be tested may not be intuitive to humans.
