Grades will be based on the percentages below. Curve will be applied if needed. The grading scale without a curve is the standard 90-80-70-60 (or more precisely with the +'s and -'s: 97-94-90-87-84-80-77-74-70-60), those grades you are guaranteed (i.e., 90 and above guarantees an A), but the curve may improve your grade.

Exam 1: Tuesday, Oct 27th, online/gradescope.

Exam 2: Tuesday, Nov 24th, online/gradescope. (On material since exam 1)

Quizzes: weekly, on gradescope. Lowest quiz score will be dropped.

Final Exam: Wednesday, Dec 16, online/gradescope. (Comprehensive)

Homework: Weekly, webassign, 15%

Quizzes: More or less weekly, gradescope, 5%

How the grade is computed:

40% (The higher of Exam 1 or Exam 2) + 40% (Final exam score) + 15% (Homework score) + 5% (quiz score)

Exam/Quiz Policies: Open book (the course textbook and your notes), but no internet use, no calculators, no software, and you must work on the exam/quiz on your own without help of others. Academic integrity is taken very seriously, especially in these online times.
