Homework assignments will be posted Wednesdays , a week before they are due - you will have a weekly quiz based on the homework problems, lab work, 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. There will also be lab worksheets. These problems will be handed out in your lab meetings, and due at the start of lab the following week.
