Your semester grade will be based on the following aspects.

Guidelines For Written Work

Your written work should be neat and complete, with the problems answered in the order they were assigned, and clearly marked. Staple your assignment into a single packet to be graded. If your paper is messy or disorganized from revisions, erasures, etc., then you may need to recopy it. Show your work, and give simplified answers. If a classmate were to read one of your solutions, she or he should be able to understand what the problem was and how you solved it. In other words, your solution should be well-written and self-explanatory. At the top of the first page of your assignment, write the short pledge

I have adhered to the Duke Community Standard.

and sign it (and print your name).

In the case of group work, each group submits a single report. Only group members who have contributed to the work may sign the pledge and write their names on it. They can not allow another group member, who has not contributed to the work, to sign or write his name.

You are encouraged to work with others on homework, as well. Here, however, you submit work individually, and the written work that you submit must be your own. In particular, you may not copy someone else's work or allow them to copy yours.

Late work? No. (Except in extreme circumstances beyond the student's control.)

Depending on time constraints, perhaps only a subset of your submitted work may be graded. In order to ensure full credit, do all of the assigned problems.
