Posted Sample Final Exams

        Sample final exams are posted in Quercus with answers to multiple choice and solutions to short answers. Every effort has been made to ensure that the answers are free of errors, but there is no guaranteed for that. Let Dr. Yu know by email if you see any errors in the answers. These sample exams are the real past final exams given before. Your final exam may cover more or less material than the sample exams.

Format of Final Exam

Part 1.    Short Answer questions (must show your work to get marks).

Part 2.    Multiple Choice questions (select the best answer, no part marks).

Details on writing the Final Exam on Quercus:

1. Login to Quercus before 9:00 on Thursday August 19, 2021. Final exam starts at 9:00 and ends at 11:20. This time includes doing the exam and uploading the answers. The exam is designed as a two-hour exam, but 20 minutes are added as buffer time for file uploads. That is, the process of “file upload” is part of the exam. Do NOT email your answers to Dr. Yu. All answers are marked from Quercus only. If you cannot do “file upload” in a question, you will not get the marks for that question.

2. Select ECO220-L0101/0301.

3. Select Term Tests and Final Exam. Select 2021-08-19 Final Exam-E220.

4. The exam has two parts.

○ Part 1 is Short Answers, about 50 points (exact points to be updated). You need to show your work. You need to do “file upload” for each question to answer the question.

○ Part 2 is Multiple Choice, about 50 points (exact points to be updated). Follow the Quercus instruction to select your best answer.

○ Once you have selected 2021-08-19 Final Exam-E220, you can view all test questions. You can scroll back and forth in both Parts 1 and 2. You can answer any question in the order of your choice. In Part 1, if you change your answer in a question that you have done the “file upload” before, you need to do a “file upload” again with your corrected answer. Your new “file upload” replaces the previous “file upload”. Quercus only keeps your most recent “file upload” and treat that as your answer. Similarly in Part 2, Quercus only keeps your most recent selection in multiple choice as your answer.

○ For “file upload”, only the formats in Word, PDF, jpg, or TXT are acceptable. Markers cannot open files in other formats and will give zero marks to the questions in other formats.

5. In Part 1 Short answers, write your answers on blank white papers with a black (or dark colour) pen. This is to ensure that the marker can read your answer. Include your photo ID (such as your T-card, driver’s license etc.) with your “file upload” in Question 1. In the remaining of the exam, you do NOT need to upload your photo ID.

6. At the end of the exam, you must hit “submit quiz” to submit your answers to Quercus. After the “submit quiz”, you have “handed in” your exam and you will not be able to make changes to your answers.

● If you want to ask a question during the test, email [email protected] and Dr. Yu will reply to your email quickly.

● If you have a system or Quercus issue during the test, contact [email protected], 416-978-4357.

● Each student is writing a unique exam which is different from other students. Students must do the exam independently.

● Make sure that you can do “file upload” in each question in Part 1 of the test. Only files uploaded in Word, PDF, jpg, or TXT formats will be marked. You do one file upload in each question in Part 1.

Trial Test

There is no trial test for the final exam. The procedure to submit your final exam solutions is exactly the same as Tests 1, 2 and 3.
