I did not receive a copy either. I opted to borrow from my library ( save the trees!) And online reviews. It's good to read Discover Canada but the online review helps you sort out what's important to remember. Good luck!
Yes, that's exactly what we brought to the testing site. They only asked for it from one candidate who was not on their master list, as a verification. We never received paper invite, just email.
Indeed, being proactive is in our own interest. Good luck on writing the test. I've found the review thru Richmond Public Library to be particularly helpful, as well as the app for practice test.
