Download PASS MOCK EXAM

PASS MOCK EXAM – FOR PRACTICE ONLY –
Course: BIOL1003A
Facilitator: Zeke Williams
Dates and locations of mock exam take-up: 7:30-9pm Oct. 5 (LA C164) & 6-7:30pm Oct. 7 (ME 3380)
It is most beneficial to you to write this mock midterm UNDER EXAM CONDITIONS. This means:
• Complete the midterm in 50 minutes.
• Work on your own.
• Keep your notes and textbook closed.
• Attempt every question.
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:
•
Come to the PASS session with your mock exam complete. There, you can work with other
students to review your work.
•
Often, there is not enough time to review the entire exam in the PASS session. Decide which
questions you most want to review – the Facilitator may ask students to vote on which
questions they want to discuss.
•
Facilitators do not bring copies of the mock exam to the session. Please print out and complete
the exam before you attend.
• Facilitators do not produce or distribute an answer key for mock exams. Facilitators help
students to work together to compare and assess the answers they have. If you are not able to
attend the PASS session, you can work alone or with others in the class.
Good Luck writing the Mock Exam!!
