Due to a family illness, I will be out on Thursday. So, your quiz on Chapter 6 and 7 will be on Monday.
Make sure you review the chapters and the homework. Here are some review sites:

Try your homework problems again without looking at solutions and make sure you can do them.
Email me with any questions.
