Announcements (previous ones)

  • As announced in class, assignment 5 will be optional. The grades for the assignment portion of the course will be best 4 assignments submitted, so each assignment counts 5%. Now I will make the deal even better for you: if you submitted 5 assignments over the semester, then the assignment that was not used in the best 4, will be a bonus grade, weighing 5%. Example:
    • you submit 5 assignments and got: 50%, 60%, 70%, 80% and 90% respectively
    • the assignment portion of your course grade will be (60+70+80+90)/4 x 0.20 = 15%
    • you get a bonus grade of 50 * 0.05 = 2.5%
If you hand in 4 or fewer assignments, then there is no bonus grade. This is one way you can boost your grade if you didn't do so well in the midterm.


  • Due time for presentations is now 7pm the day before: no exceptions after that. Future groups, please make sure your names appear on one of the slides. Thanks.


Important announcement regarding the take-home midterm and assignment 5.

From speaking with your class members, I've realized this term is just too crazy with final projects and hand-ins in your other courses. The value you will get from a take-home midterm is about that from a large assignment. Rather than having your do the take-home midterm and assignment 5, I'd rather you do one thing well. So I'd rather you do assignment 5 (which will posted soon), so you have seen an equal number of questions from all topics in the course. The take-home would cover the entire course, while assignment 5 would focus only on recent material. If I cancel the take-home, this leaves 10% of your grade unaccounted. Here's what I propose (note, it is not confirmed yet).

  • Drop the take-home midterm and
  • transfer its 10% overall course grade to:
    1. the final exam, OR
    2. spread it out equally over the entire course (i.e. divide your final percentage by 90 instead of 100)
and then take either option 1 or 2, whichever is greater to be your final grade.

How does this proposal work for you? Let me know your thoughts by Wednesday and I will make a final decision based on the class consensus. Note that assignment 5 will still be optional as described above, but of course I strongly recommend you do it.
