I’ve just finished the second of two exams this week. I’m pretty sure I failed both of them, but that’s okay. In fact, I’m really happy about it because I now know at least one path I don’t want my career to take. The reason for this post, however, is because of the severe cramp I have in my right hand. My exams have always tended to be a lot about numbers, and today I sat a paper that was more about theory.
