10/19: Scores for Exam 1 are posted on the course moodle page. A summary of the distribution of scores is here.
10/17: I will try to have the exams graded and ready to return to you by Thursday class, but that might not happen; if not this Thursday, then I'll have the graded exams for you by next Tuesday. In the meantime, here are my solutions to the exam if you want to take a look.
10/12: At students' request, I pushed the exam start time back 30 minutes. So, the exam will be Tuesday, October 17th, 9–11am.
10/11: Solutions to the review problems are here and solutions to the old exam are here.
10/08: For lab this Tuesday (October 10th), the TA will do some review activities, e.g., answer students' questions about previous homework problems, discussion some of the exam review problems, etc.
10/06: Here is some various information about our upcoming exam, on Tuesday, October 17th.
- The exam will cover all the material in Chapters 1–3, excluding Sections 2.4, 3.4–3.6; Section 3.6 will be part of the material for Exam 2.
- For the exam, you may use a one-page (front and back, regular size paper) sheet of handwritten notes. Feel free to write whatever you want on this paper, the only condition is that it be handwritten, not printed out.
- Here are some practice problems, some are fairly easy and some are less so. This is just to give you something to think about, there is no need to answer write out solutions to all of them.
- Here is the exam I gave last fall, which was based on a slightly smaller chunk of material than what we have covered so far. Note that this exam was "too easy" and that I will try to make the exam harder than this one; but this is still useful as it gives you some idea about my style of questions.
09/26: There are now some (rough) notes for the lab sessions posted below.
09/20: Just a reminder that October 5th is fall break so we will not have class that day.
08/23: The first homework assignment has been posted, see below. Also, I have activated the Moodle page for this course, where I'll be posting your grades, so please check to make sure you can see it.
08/23: I've posted my office hours: Thursday 11am–12pm.
08/17: Grades for this course will be posted on "moodle", which can be accessed from the WolfWare website here. Please check your grades occasionally to be sure that your scores have been recorded correctly.
08/17: Here are a few important dates—I will remind you of these things in class when the time is near.
- There will be no class on Thursday, October 5th, for Fall Break or on Thursday, November 23rd, for Thanksgiving.
- The midterm exam is tentatively scheduled for Tuesday, October 17th, and the final exam will be held on Tuesday, December 5th from 8–11am, based on the schedule set by the university.
