I only ever get SA questions right when I map, but that pushes me over time. Anyone have tips for moving from working it out on paper to doing it mentally? Is it just a matter of doing it enough times on paper that it becomes more intuitive?

almost fell for the confusing necessary for sufficient trap on answer c

on this one wouldn't it be easier to just use intuition than to reason... it would take me well over 5 minutes to figure out the conditional diagramming whereas the answer is pretty obvious if I just look at the stimulus. I guess if I do that too much, my "common sense" could fail me and I'd end up falling for a trap.

Ugh I'm so annoyed... If I were approaching this answer intuitively without thinking in lawgic terms A would have been the obvious answer, but it gets so convoluted when I try to diagram and end up tripping myself up over the all before some issue (which I now understand why it's not applicable here).
