It ain't rocket science, as long as you know ACTS and PROVE and religiously apply them you will pass, CORE (I assume this is some sort of hunting test) varies from province to province so I can't help you there. Basically keep your booger pickr off the bang switch at all times, and don't even think of pointing the thing at you or anyone else's noggin to "examine the bore" until you've done all the other steps (I did them twice, instructor after it was all said and done asked why, I simply replied that "I don't like the idea of having a gun pointed at my face, even when I'm the one pointing it"). Passed with something like 95%, there was one question about shotgun chokes that I ended up getting backwards.
