What are they? When are they?

• Problem sets will be distributed roughly once a week.
• Problem set questions are designed for the most part to go beyond the reading and give you an opportunity to apply the concepts you've read about in a creative way.
• In many cases, multiple answers are possible.
• Questions on the exams will be taken from the problem sets, with relatively minor changes.

• We will spend considerable time in class considering specific problems, but there will be no time to go over all. You are highly advised to address each problem set completely as it comes out and not put it off shortly before the next exam.
•  Information may be crammed, but concepts generally need incubation time. Problem sets are insight rich, information poor.

• Suggested answers will occasionally be provided for some but not all problems.
• However, you are encouraged to contact either of us for confirmation that you're on the right track or have reached a good destination.
• We may collect your answers to some problem sets (announced well in advance), and grade them on the basis of effort. The grade will be applied to the next exam.
