Right now, show all of your work to the Honorlock proctor by holding up each piece of paper in front of your camera, that you intend to upload in Canvas after the exam.   Within 30 minutes after completing the​ exam, scan or take a picture of each paper containing relevant work and upload each under the appropriate test in the Canvas drop box attached to the study guide.  You do not need to upload your study notes.   ​By uploading your​ work, I am able to give partial credit on missed problems.  Some problems may require work to be shown for any credit.     ​Finally, please note that the automated grade for this test is NOT correct. I will be grading these exams by hand and providing feedback below the problems.  You may view this feedback by clicking on the test in Canvas Gradebook. It may take roughly one week after you take the exam to receive your official score.
