ECON 1001 Mock Final
It is most beneficial to you to write this mock midterm UNDER EXAM CONDITIONS. This means:



Complete the midterm in 3 hours.
Work on your own and attempt every question.
Keep your notes and textbook closed.
After the time limit, go back over your work with a different colour or on a separate piece of paper and
try to do the questions you are unsure of. Record your ideas in the margins to remind yourself of what
you were thinking when you take it up at PASS.
The purpose of this mock exam is to give you practice answering questions in a timed setting and to help
you to gauge which aspects of the course content you know well, and which are in need of further
development and review. Use this mock exam as a learning tool in preparing for the actual exam.
Please note:

Complete the mock exam before attending the take-up session. During the session you can work
with other students to review your work.

Often, there is not enough time to review the entire exam in the PASS workshop. Decide which
questions you want to review the most – the Facilitator may ask students to vote on which
questions they want to discuss in detail.

Facilitators will not distribute an answer key for mock exams. The Facilitator’s role is to help
students work together to compare and assess the answers they have. If you are not able to
attend the PASS workshop, you can work alone or with others in the class.

PASS worksheets and mock exams are designed as a study aid only for use in PASS workshops.
Worksheets and mock exams may contain errors, intentional or otherwise. It is up to the
student to verify the information contained within by attending the PASS workshop.
Good Luck writing the Mock Exam!
