Do not attempt to run the practice test (or any other Canvas test) at the same time. It will not work
only result in all your answers being lost. You must close the practice test first.
Do not run any other programs at the same time or attempt to switch between the test's browser w

There are different types of questions. Some might be multiple choice, some might be numerical
answers, some might be 'fill in the gap' questions, etc. In the case of multiple choice, there could be
or more than one correct answer.
You will get your results automatically after the closing date (that is, after the end of test period) thr
Canvas for a limited time period.
Questions are randomly selected from a large pool of questions, so students are likely to get differe
questions in different order.
This is an open-book test. You are allowed to consult the unit's material during the test.
