We will be using a computerized grading system called Mastering Physics. It is the same system as used last semester in 227. 

Here are the basic things that you need to know about the homework.

• There will be 13 assignments during the course of the semester.
• The assignments, unless otherwise noted, will be due at 10pm Monday evenings. You should, however, try to complete the assignments before the weekend. On weeks after the common hour exam, you will receive a homework extension to 10pm on Wednesday.
  
• You are very strongly encouraged to submit the homework on time. However, even if, for some reason, you can't submit on time, it is still important that you do the homework. That's how you'll learn the material. For that reason, we will grant partial credit on a sliding scale. Credit for each assignment will decrease to 25% over the course of 9 hours after the due date. For example, at 1 am it will be worth 75%, at 4 am 50% and at 7 am 25%. It will then remain at 25% for the remainder of the semester.
• You are allowed 6 attempts at the solution for each part of each problem.
• If you get stuck on a problem, you can ask Mastering Physics to give you a hint. You are strongly encouraged to use these if you are really stuck. In order to encourage you to think hard about the problem before requesting the hints, you will receive a bonus of 3% for each unused hint.
• Your lowest two homework grades will not count against you. At the end of the semester, we will find the two homework assignments for which you lost the greatest number of points. We will then give you full credit for those assignments.
