Grading Policy  

Rubric: Weekly Quizzes: 30%,       Mid-term exam: 30%,       Final exam: 40%

Quizzes: Held weekly via CANVAS. Each Quiz will have five multiple choice problems, three options given, only one option correct. You need to choose the correct option. Nothing to type. No make-up quizzes if you miss. See Weekly Quiz tab in the left menu for details.

Exams: Both Mid-term and Final exams will be held as CANVAS Quiz.

Passing grade: C or above.

Academic honesty (zero-cheating policy): Any form of cheating or dishonest academic activities (for example, communicating or sharing screenshots with another student) during quizzes or exams will not be tolerated and such students will receive a failing grade. Any students with such activities, if caught by the instructor, TAs or classmates, will be reported to the department and her/his college provost.
