Lecture Notes

You can see your grades and access the lecture notes at the Learn@Illinois website.


There will be three midterms and one final exam. All exams will be closed-book and closed-notes. No calculators or other electronic devices will be allowed.

Midterm exams will be during class time, in our classroom. Make sure your solutions are clear and organized, and include all the necessary details. Merely writing down the answer without showing any work will receive little or no credit.
