You can do the test only once. (Note: This is different from the practice test

like.)
Please use a modern browser with the latest updates installed (Chrome/Firefox recommended).
You must have JavaScript enabled for the test to work correctly.

requirements.
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
and any other browser window. Chances are it will shut down your test and all answers will be lost.
The test has a maximum time of 60min. After 60min, your answers typed in by then are automatica
submitted. You can submit early, if you are done with the test, by clicking on the "Submit" button (c
"Next" first, then on "Submit" on the next page).
You cannot interrupt or pause the test. Once you started it, the clock is ticking.
It is your responsibility to ensure that you have a stable network/internet connection if you take this
off-campus.
Everything from week 1 to 6 is potentially in this test. You should consult the lecture slides, tutorial
lab notes, and the textbook in preparation for the test. Not everything can and will be discussed in c
Reading the textbook and additional resources, as pointed out by us, is your responsibility.
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.
