Use the Discover Canada guide that was included with your test invite. Read it a couple times and pay attention to the boxes with information on the pages. That is all you really need to prepare for the test.
Due to confidentiality discussing the test questions are a no no so you aren't going to get anyone to give you specifics. On top of that, there are several different tests and the people sitting around you will get a different test to the one you are given.
Thanks for reply, to clarify I am not expecting to get the specific questions. Just wondering how different real questions are from the one we can find online. Also in order to pass we need to answer x out of ?
