When you have completed the exam, be sure to document your work as described in the video posted earlier in our course Canvas site.  Take this moment right before submitting your exam to show your handwritten notes and work to the camera to have all opportunities to earn credit for your work. As shown in the picture below. Once you have completed all questions, documented your work in HonorLock, and submitted the exam, you will need to upload a pdf of the written work in a separate assignment. The link for this is a separate assignment in Canvas.  The file must be sent within ten (10) minutes of the time that you submit the exam.  The work will need to match what you have shown in Honorlock.  More information is available in the announcements in our course canvas site.  All the best.
