Well, I had my test years ago, and yeah, it was simpler than some of the tests you find online...
If you score well in these, there's nothing to worry about.
 
Scored 20/20 last week on Feb 11. I did practice questions from
https://www.torontopubliclibrary.ca/new-to-canada/citizenship.jsp
https://www.yourlibrary.ca/citizenship/
Also read the sticky discover canada post summary twice and that’s it.
My two cents, try to study the discover canada and keep it simple. Majority of the questions were simple and easy to answer. If you didn’t give this test it’s due prep time, it’ll always be difficult. I prepped for it for about 3-4 days and found it to be relatively easy. Hope that answers your questions.
