Class will start on Monday Aug. 26. I intend to use this blog for posting written responses to student questions. (Most questions I'll answer orally, but for particularly interesting or widespread questions, I like to provide written responses.) Later in the semester, you should also find it useful to look at some of the old exam questions and answers posted here to anticipate what the exam will be like. But some of these old questions address material that I won't discuss this semester. Struggling with them won't be helpful. In addition, I strongly discourage you from reading any of these old exam questions until we are sufficiently advanced in the course. I'll let you know when the time comes.
