She went on to tell them how those exams were marked. “At Cambridge University, where I teach,” she said, “you can get a First, a 2:1, a 2:2, or a Third”. This seemed like surplus information. But then she got to her main point: “Who gets a First? A crazy genius gets a First. They’re mostly boys, I have to say,” she added, shaking her head. “They’re sociopaths. And show-offs. And they’re unemployable by anyone other than another university. Girls get 2:1s. And they could have got those months before the exam. They come and see me when they’re revising and I say: ‘Stop! Your wheels are spinning!’.”
