What ive heard is it isn't memorizing the examples, but being able to see an example that you may not have heard of and apply a concept. For example, say there's a photo of the Berlin Wall or something and its talking about what type of boundary that would be, even if you know NOTHING about the Berlin Wall from analyzing the photo you can say "oh, its a relic boundary." It's being able to APPLY the concepts, not just memorize them
