Homework is assigned on a regular basis. It is not collected but you are welcome to turn (part of) it (you'll get it back with my comments which might be helpful as part of your tests' preparation).
There is a quiz, two in-class tests, and a Final.
Grading policy: attendance=1 unit; quiz (Mon, Feb 12) = 1, two tests (Thursday, 3/8 and Wed (=BU Mon), 4/18; two units each); Final (Tue, 5/8, 9am-11am) = 4 units. The lowest from these 10 grades will be dropped. The average of the remaining nine units will determine the grade for the class.
The students have the responsibility to know the provisions of the CAS Academic Conduct Code, copies of which are available in CAS 105. Cases of suspected academic misconduct will be referred to the Dean's Office. Only documented reasons for a missed quiz, test, or lecture might be taken into consideration.
