Dunno, never practiced them. There's nothing heroic about having aptitude, many people have it.
I highly suspect that the practice tests are not the same as the real tests, you might get good at repeating the same test over and over again but have a go at different one...
I doubt they were written for a laugh, more likely to cash in on someone's doubt about their ability because, let's be honest, they aren't particularly onerous are they.
