Homework assignments will be posted Wednesdays , a week before they are due - you will have a weekly quiz based on the homework problems and the concepts they test, at the end of class on Wednesdays. A subset of the weekly homework problems are underlined and bold-face, and at the start of class on Wednesdays you will hand in carefully written up solutions to this subset of the homework.
homeworkguidelines.pdf for written homework (thanks to Victor Camacho from a class a long time ago).
