The course grade will be calculated as follows, out of 660 points total:
You can check your grades via Moodle.
Your grade total will be converted to a letter grade according to the following scale:
|A+||≥ 630||B+||≥ 520||C+||≥ 450||D+||≥ 380|
|A||≥ 570||B||≥ 490||C||≥ 420||D||≥ 350|
|A-||≥ 540||B-||≥ 470||C-||≥ 400||D-||≥ 330|
It is possible to take the course for 4 credits rather than 3, at the cost of extra homework questions and more difficult exams. If you want to do this, you need to register at the math office in Altgeld Hall soon after the start of the course.
There will be 10 homework assignments, to be turned in at the beginning of class the day they are due. Of these homework assignments, the top 8 homework scores will determine your grade. Each assignment is graded out of 20 points, for a total of 160.
If you cannot attend class, you can submit a scanned copy or a photo of your homework as a PDF file by e-mail before class begins. Please avoid doing this unless it's necessary, since it is more work for the grader.
If the homework assignment is received after class on the due date, but before the next class, it will be accepted as late, for a 2-point penalty. Homework will not be accepted after the next class for any reason.
There will be three evening midterm exams: Wednesday 2/13, Wednesday 3/13, and Wednesday 4/17 from 7pm to 8:30pm in 341 Altgeld Hall. Correspondingly, three lectures will be canceled, not necessarily in the same week as the midterm exams. The first of these is already marked in the syllabus below.
The final exam will be on Monday 5/6 from 7pm to 10pm in 311 Gregory Hall (our usual classroom).
This course is based on several textbooks with a lot of overlap; read whichever ones help. In the syllabus, I will refer you to sections of the textbooks below that cover the relevant material.
The syllabus below will initially describe a tentative plan for what topics will be covered when. As the semester progresses, I will update the syllabus with information about what actually happened in class, adjustments to my plans for the future, and links to homework assignments.
