Quiz Instructions
This practice exam is designed to help students become familiar with how a timed Canvas quiz exam
works, and to indicate the question types that will be on the INFO30005 exam (written text, coding,
multiple-choice).
Unlike the real exam, you may take this practice exam any time, and do it multiple times. The real
exam:
will only be available at your scheduled exam time
can only be done once
will have different questions
We recommend that you take this practice exam using the same hardware/software platform with
which you plan to take the real exam - this will help you become accustomed to the user-interface.
Things to note about the user-interface of the quiz:
a timer at the top-right of the page shows how much time you have left
a list of questions at the top-right shows which ones you have already answered
your answers are auto-saved
when you have finished the quiz, you need to press the Submit Quiz button at the bottom-right of
the page
