Congratulations! I know what it feels like to fail such an exam multiple times before passing and I know the relief you're feeling. Do you have any idea how different the test is in Canada compared to the US, with the exception of the in person flight review, which we don't have? Is the written part on par of flat out more difficult?
No idea what the American test is like, but the test I wrote for the basic certificate had a lot of questions that didn't relate to flying a drone. Some related to flying a model airplane, and quite a few related to flying an aircraft.
I can't (legally) repeat the questions exactly, but I failed one because I didn't know the most common method of launching a sRPAS*. Turning on the motors and going straight vertically wasn't one of the options. Apparently if I flew RC model aircraft that would have been an easy one**.
I managed to pass the question that required I knew what controls are in a helicopter, thanks to childhood reading. Hint: it's nothing like the DJI controller controls
I got several questions about clouds and procedures for flying in them, which was odd given that the basic certification I was writing the test for required VLOS to be maintained with no exception.
I passed the questions about hypoxia, both what it is and its effects on vision, mostly because that was part of one of the lessions I taught in grade 10 science. Still don't know how that relates to flying an aircraft when your feet are on the ground. The questions on icing kinda made sense but the answers assumed you were flying a fixed-wing aircraft (and again, assumed you were flying in clouds so beyond VLOS).
The advanced test is longer, has a higher passing mark, and you have less time — I doubt I would have passed the advanced test my first time as I needed most of the time for the basic to get a good mark. (Good enough to pass the advanced test, but it wouldn't have been without the extra time.)
I like the idea behind the Canadian system, but I think that the test needs to be revised to better reflect knowledge that an actual sRPAS pilot needs. Something like flyaway procedures would make more sense than hypoxia.

**Thinking about it, the most common way of launching drones (hand-launching) would have been marked wrong.
