These are questions that are available shortly after each lecture and remain posted for only 24 hours following the lecture. The objective is to have you go through the questions soon after each lecture as a way of self-assessing probe your current understanding. Then, depending on how well you know the answers, you can adjust your learning accordingly. In other words, use these questions to test your own retention of the material and/or to highlingt gaps in your understanding that you need to fill. Answers will not be posted, so for questions you're ot sure about, exhange answers, work together, ask your TA...whatever...but use this option as a way of directing your own learning to make your time as efficient and effective as possible.
