For the argumentative writing section, should I be drawing from outside sources? I did one of the practice ones on LSAC and I didn't think the instruction was clear enough. And am I to argue from one of the positions that LSAC gives samples of in response to the prompt? I know everyone says its akin to a "are you a human" test but I don't want to screw up on something easy like this for some technical or simple reason.
