Hey!

For the life of me, I cannot understand the level 5 difficulty questions for PSA. I can get the lower and medium difficulty questions correct, but it seems like the higher difficulty just isn't clicking. Does anyone have any tips or mental strategies for how they approach difficult PSA questions? I think I'm getting lost in the answers (and I believe my most common mistake is confusing sufficiency/necessity language even though I'll have it diagrammed properly!!)
