If you don't take either the course or swallow the manual, there are questions that will trip you up. The important thing to remember is the book was written by legally-minded people and not practical shooting people. Some of the teaching points make me cringe, like looking down the muzzle of a firearm.
There was a nonsponsor who would spam you with a daily examination quiz question. If you goofle Dave Bartlett in eastern Ontario, I think you will find his firearms training dot ca site. I've known the man for a decade and took some recertification course from him (I forget even why).
