Obviously, you're an idiot.
Although I just posted this in a comment on Chai's site, I thought it was too perfect a statement of my testtaking abilities not to post here, too.
I was doing some multiple choice questions earlier, and as you may well know, the answer section will not only discuss why A is the right answer, but also why B, C, and D are wrong.
So, I picked D, right? Wrong. After reading why C was the right answer, it then stated, "D is obviously wrong." Well. Is it too late for a bar refund?
