With all of the sats and gcse threads about now, I keep thinking about one of my sats questions being ‘what is the only egg laying mammal’? I was frustrated as we hadn’t been taught the answer. My entire class had put penguin even though we knew it was wrong. We’d never heard of the duck billed platypus which was the answer they were looking for. And we now know about the multiple species of echidna. What answers did you put that would be wrong now?
