You may revise your work on Assignment 3 or 4 (but not both!) for credit. Here are the rules:

Please hand in your revised work, with a fresh write-up describing your experience completing these revisions, in class on the due date. Include your graded original submission.

If you do not have your graded original submission to resubmit, you must email me ahead of time to let me know why you do not have it. Note that you will not have this graded original submission during your review for the upcoming exam; you may wish to make a photocopy of it.
