|Thu 12/9||HW4 & 5||HW4 grades are posted. I hope to have finished grading HW5 by this evening.|
|Thu 12/9||Final Projects||I must have my grades in by noon 12/21 at the absolute latest. I am leaving for Amsterdam next Thursday 12/16 at 6pm. If you are not finished by then, I will grade them over the weekend. Please submit your materials to CMS. If you have more than one file, please put them in a .zip archive. CMS is set not to accept submissions after 11:59pm EST 12/18.|
|Thu 12/9||Final Exam||The final exam is ready for those who wish to take it. 72-hour takehome, open book and notes. Submit the completed exam to CMS. No collaboration please. Send me email for clarifications.|
