The course will have a number of homeworks that are designed using the Gradiance technology. The objective of these homeworks is to enable everyone to get 100% and learn the underlying material. While questions look like multiple choice, you should think of them as more conventional "solve this problem and submit the solution" questions. That is, you are given a problem to solve, which you should work completely. Then, you are given a random choice of responses that are designed to figure out whether you got the right solution or not. If you do have the right solution, you should be able to answer the question easily, regardless of the choices presented. If you get it wrong, you will be given a hint and allowed to try again. Your score on a homework is the maximum of any try. We group about 5 questions together, so you can't repeatedly guess each question independently, without actually doing the work.
