Idiot tests. They may as well just invent a hand that shoots out of your monitor and slaps you in the face, because you really are that much of an idiot.
Don't bother playing The Ultimate Idiot Test, because it'll just reinforce the negative self-image you have. The Ultimate Idiot Test is the usual button-pushing nonsense, but with added terrifying tasks like real maths and elementary symbols. You're going to fail The Ultimate Idiot Test. Just don't play it. Honestly.
