[Sorry for the belated response; I had set up WebBoard to notify me of new "Questions for the Instructor", and was relying on it to do so, but for some reason it must not have worked. I have redone this, and will also manually check the conference for new postings]
In addition to questions about the schedule, it took some time for a number of students to fully understand the structure and the requirements, and I have rec'd a number of requests for extensions to submit postings. To address these various concerns, let me suggest that anyone who HASN'T posted responses to Sections S thru C, to do so before completing the first test (the deadline for which I have extended to 4/30). We will start Section D 4/29, and I'll try to make the schedule and assignment dates as clear as possible!
