Grade Distribution - There is a homework, midterm, and a final 

How your grade is calculated
40% Final
30% Midterm
30% Homework

Reading 

Readings will be assigned each week from the reading made available online.  

Lectures

We have lecture in person MWF 11:30 to 12:20 in PAA110.  

Homework

Homework will be due weekly on midnight Friday.   Homework should be converted to PDF format and uploaded each week by its due date to receive full credit. The two lowest homework scores will be dropped.

Homework shall be submitted on Canvas as a PDF file. Late homework without an extension will be discounted by 25% per day to a minimum of 50%, and will not be accepted after the last lecture class.   If you need an extension for any reason, please contact the instructor by email before the homework is due.

Office Hours

Office hours will be arranged with the class and extra remote office hours announced when lectures are cancelled.

Contact instructor to arrange special office hours.

Exams

Midterm is scheduled for normal class time and room on Feb . 14 .

Final exam is scheduled for Wednesday March 18 2:30-4:20pm in our normal classroom.

Schedule

Grading

Exams will be curved upwards if the mean is below 65%.  They will not be curved downwards.  Average exam grades combined with completed but mostly incorrect homework and reading quizzes should yield a GPA of around 2.5.

Getting Help

Please do not hesitate to contact the TAs or the instructor via email if something is going wrong in the class that we can help with.  This includes difficulty with certain concepts or preparation, concerns about grades, or personal issues that have come up that are interfering with the course.  The earlier these issues are raised, the more likely it is that satisfactory accommodations can be made.
