Stupid bloody practice exam

So I've got a multiple choice exam for Social and Developmental Psychology, and you know me, revision isn't really something I do, though I am trying to get better at it. There's a practice paper online, and I've run through it to see how much revision I need to do, see how much or little I know. I've got 23/25, but I cannot figure out which bastard two bastard questions I'm getting wrong! I should probably do an hour or so's revision...
