Your allowed talk about the setting in literary genre is this pretty much the same as what you would say for cultural context such as location time period???
Literary genre isn't up this year I believe, either Cultural Context or General Vision and Viewpoint. SO You are fine wit not doing LG!
Literary Genere is up this year , but as it came up last year it's not a high contender , however it's still one of three possibilities so I'd have it half learnt just in case.
Setting is part of LG , just remember to talk about that it impacts how the story is told :-)!
