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: Thursday, Jan 28th, online/gradescope.

Exam 2: Thursday, Feb 25th, online/gradescope. (On material since exam 1)

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

How the grade is computed:

40% (Exam 1 and Exam 2 each 20%) + 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.
