Only for questions 5, you are allowed to use paper submission. Please draw the diagram(s) on a paper and submit it. For the schema from the ERD use submission over canvas. Please remember to submit the paper within 10 minutes of your respective submission of the final exam over Canvas. Anything sent beyond that will not be considered for grading. Also please make sure your handwriting is readable. Also submit the scratch paper that you have used during the exam.   For all the questions try to explain the intermediate steps. Just providing the answer will give you only 1 point for the question. Also even if you do not get the final answer right, showing me the steps will help you to get partial credits, which is more than 1 point. In case you have any questions please write an email or join the Zoom Call. Also please take your time in answering the questions, please donot rush and read them carefully. https://psu.zoom.us/j/96938983918?pwd=piKUiSupaauwq3lNwai4g29wlDHDt9.1

You will have 2 hours and 50 minutes (almost 3 hours; shown as 2:50:00 in the upper right corner of your screen) to work on the exam; starting from when the questions first load.  You will be unable to make any more changes after 2 hrs 50 mins from the time you start the exam AND you will be unable to start the exam after 11:59 pm (end of the day) on Monday, Dec 16. If you lose internet access, the timer will not stop, so you will still only have 75 minutes from when you started before your exam will be over. If your normal internet connection is unreliable, please find a different place to work. You could bring your laptop to campus and use Normandale’s internet OR you could use one of the computers in Normandale’s computer labs. If you plan to work from a different location, TRY IT FIRST with the Pre-Exam Agreement, especially if it will not be at Normandale (since you will need to download Honorlock and have access to a webcam.)  Which of the following is true? (Choose any/all correct answers.)
