Hi all, after some thought, I have decided to extend the deadline for Assignment 2 to 9 am, Wednesday, February 20 (effectively, roughly 1 extra business day, given that Monday is a holiday). I realize that the course has been moving very quickly, and I want to make sure you all have the time to seek help and get extra practice before the assignment is due. On that note: I'll try to build in time on Wednesday for some review of Module 4, and will also be moving some of the planned content for the week to the subsequent week. I imagine we'll have time in the last week for spillover content. In any case, I'd rather you all learn a few things well than many things not so well.
Please do not hesitate to get in touch if you feel overwhelmed or if you have suggestions to share. Thank you all for your flexibility as we work things out during this first, trial year.
