You will submit your exam on Courseworks as you would a homework assignment. Submissions will no longer be available after 9PM, and no exceptions will be made to this. You should, therefore, plan to start submitting plenty of time in advance of 9PM, so that you can contact me if there are any unexpected technical issues. I suggest that you stop working by 8PM and start submitting then. Honor code This is an open book, open note exam; the book and the notes on Courseworks are the only authorized material for this exam. In particular, you may not refer to posted homework or practice midterm solutions; you may not use a calculator; you may not use other online references or tools; you may not communicate about the problems with other students. Any violation of this policy will be pursued as academic misconduct, as will any failure to report academic misconduct. You must sign and submit the following statement1 when submitting your exam. (If you don’t have a printer, copy the statement onto a piece of paper, sign below it, and submit that.) I affirm that I have not plagiarized nor used unauthorized materials in taking this exam, nor have I given or received illegitimate help with this exam. Signature: 1This statement is modeled on the Columbia College code of honor. Page 2 of 9Calculus IV PRACTICE MIDTERM #2(b) 11/15/2020 1.
