As I write this (a week before classes start), I envision four homework assignments, each worth 20% of the semester grade, and a final exam worth 20%. I may change this somewhat as the semester unfolds.
Exams must be taken at the scheduled time, unless arranged in advance or prevented by a documented medical or family emergency. If you have three or more exams scheduled on the same date, or a religious holiday that conflicts with an exam or assignment due date, please notify me in writing within the first two weeks of the semester in order to receive due consideration. Exams not taken without one of the above excuses will be recorded with a grade of 0.
Homework assignments will be accepted late, with a penalty of 1/3 per 24 hours or portion thereof after they're due. An hour late is 33% off, 25 hours late is 67% off, and after 48 hours don't bother turning it in. It's still a good idea to do as much of it as you can, however, because I'll assume on the exams that you've done the homework.
