The entirety of the exam can be found under this question. Open the file within Canvas and stay on this page while you take the exam. DO NOT DOWNLOAD THE EXAM PDF AND/OR OPEN THE EXAM IN A SEPARATE TAB.  Work through each problem on a separate sheet of paper and make sure that you number/label each problem appropriately and include all of your work. You are not required to rewrite the problem statements on your work so long as you label them clearly. You may use multiple sheets of paper for a single problem, but no sheet of paper should include work for more than one problem. Box all of your final answers. When you are done, answer the true/false question below and then “submit” your exam through Canvas. Once you do this, you will have 15 minutes to scan your work and upload to Gradescope. I will then grade your work on Gradescope and update your Canvas grade to match. If you are shown a grade for this assignment after submitting here (such as  100 or 0), note that this grade is not necessarily correct and does not have any relationship to your graded work submitted through Gradescope.   Academic Integrity Statement: I certify that I have not violated Penn State’s academic integrity policy in taking this exam. I have not seen any portion of the exam before taking it, nor will I reveal the contents of the exam to any other student in the course after taking it. I have not accessed any outside sources in taking this exam, including, but not limited to, official course materials, personal notes, online sources, or any form of artificial intelligence. All work to be submitted through Gradescope is my own, and all such work occurred during the 90-minute exam period (i.e. I will not write down additional work/answers between the time I “submit” this exam through Canvas and the time I submit my work through Gradescope).
