Weekly Homework Policy

Completing homework assignments is an integral part of this course. Problems are designed to reinforce concepts covered in lecture as well as to encourage students to explore implications of the results discussed in class. Very few students will be able to go through the entire course without struggling on many problems, so do not be discouraged if you do not immediately know how to solve a problem. In confronting difficult questions you should consider how the problem at hand connects to topics, definitions and/or theorems discussed in class.

When you have worked on a problem for a while and remain stuck, you are encouraged to ask for hints from your instructor or TA. Students may also discuss problems with one another, but must write solutions on their own. In particular if you have taken notes while discussing homework problems with friends or instructors, you must put these notes away when writing your solution. The Honor Code applies to this and all other written aspects of the course. Be warned: watching someone else solve a problem will not make homework a good preparation for tests. Don't get caught in the trap of relying on others to get through homework assignments.

Students are expected to take care in writing their assignments. For instance,

  • never forget to put your name, your section number and your TA's name on the top of your work;
  • assignments should be written neatly;
  • assignments should contain clear, complete solutions; and
  • completed assignments which contain multiple pages should be stapled for easy grading -- one point will be deducted for not doing this.

Partial progress toward solutions on problems will be awarded partial credit, but simply writing answers down without justification will receive zero credit. Please note that usually only a portion of each week's problems will be scored (and the selection of problems chosen to be graded will not be announced in advance); as a result, be sure to look over the posted solutions to check your ungraded problems when your paper is returned.

Logistics for Weekly Homework: Assignments must be turned in to your TA (discussion section leader) -- you will not receive credit for work turned into another section leader. (If you're unable to turn in your homework in section, slide it under your TA's office door; submission to TA mailboxes is not permissible.) The deadline is 3:05 p.m. on the given due date, and no late homework will be accepted under any circumstances. (This is as much a courtesy to the grader as an incentive to stay current with the course and not fall behind.) To accommodate exceptional situations such as a serious illness, your lowest homework score will be dropped at the end of the quarter. Solutions will be posted on this page by the following morning.

Students are encouraged to pick up their graded homework assignments promptly; please make arrangements with your TA to pick it up outside of class (or via electronic scan if absolutely necessary) if you cannot attend the discussion section on the day the homework is returned. It is ultimately your responsibility to look over your graded assignment while consulting the posted solutions, not only to check your understanding but also to find any grading errors or mis-typed entries in your CourseWork grade record. If you find an error in how an assignment was graded or recorded, please appeal to your section leader (who has final authority on all homework appeals). If more than a week has passed since an assignment was returned in section, your CourseWork score entry for that assignment can no longer be changed.
