Hey Everyone,<br><br>HW4 is up. I have graded the midterm. I haven't posted the scores. Will do so after lecture today.<br>The score were a bit low, so I will give you guys an opportunity to reclaim half the points you<br>lost by studying the problems you got wrong, coming to my office, me choosing from amongst those<br>that you got wrong, you writing on my white board a correct solution and being able to convince<br>me through questions and answers that you now know how to do that problem. Such test retakes must be<br>done before the last day of class.<br><br>Best,<br>Chris
