Weekly Homework Policy

Homework is an essential part of learning. The assigned weekly homework is specially designed to reinforce the learning goals of each lecture as well as to explore further examples and consequences of the results and ideas discussed in class. Please do not be discouraged if you do not immediately know how to solve a problem: everyone has to work hard learning new mathematical ideas and applications. When encountering a difficult question, think about how it connects to topics, definitions, and/or results that have been discussed in class and on the worksheets.

If you have worked on a problem for a while and remain stuck, please ask for hints from your instructor or TA in office hours. You may also discuss problems with classmates, but must always write up solutions on your own (this helps to reinforce your own understanding of the solution). In particular, if you have taken notes when discussing homework problems with friends or course staff, you should put these notes away when writing your solution to be sure it is in your own words. The Honor Code applies to this and all other written aspects of the course.

Watching someone else entirely solve a problem will not help you to learn the material or be prepared for exams, much as watching someone else bake a cake does not teach you how to bake. Avoid the trap of relying on others to get through homework assignments, since it is precisely by grappling with the homework that you reinforce your understanding and identify the concepts or skills on which you should seek an improved understanding.

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

Partial progress toward solutions on problems will be awarded partial credit, but simply writing answers down without explanation or justification will receive zero credit. Usually only a portion of each week's assigned problems will be graded (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 over your solutions to the ungraded problems when your graded assignment is returned.

Logistics for Weekly Homework: The weekly homework submission is handled electronically via the Gradescope platform (students registered for the course at the end of the first weekend should receive an email to sign up for Gradescope; otherwise please starting on the Sunday evening preceding the second week of classes). Gradescope accepts only electronic submissions, so you'll need to scan your homework before uploading it. Make sure to allot plenty of time to follow the submission instructions here before each deadline.

Assignments will be posted no later than a week before they are due. Any change to a posted assignment will be announced in class and via email.

The due date is always Wednesday morning at noon 12PM, 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 situations such as a serious illness or anything else that may arise (even if it is an obstruction known in advance due to your schedule), your lowest homework score will be dropped at the end of the quarter; please do not use this up early in the term. A complete solution set to all assigned problems will be posted in Canvas by the following morning.

Students are encouraged to examine their graded homework assignments promptly. 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. If you find an error in how an assignment was graded or recorded, please appeal to your TA section leader (who has final authority on all homework appeals). After a week has passed since a graded assignment has been released in Gradescope, your score for that assignment will be entered into the Canvas gradebook, after which point it can no longer be changed.

All homework assignments and solutions will be posted weekly on Canvas.
