It’s 1.49am. I have completed one of the exam questions. I have comsumed several coffees, a bottle of V and almost all of a 150gram block of chocolate. I have (largely) completed the research for the other question. I am now going to bed. I have set the alarm for 5.30am. That should be enough time to finish it and file it by the 10am deadline. I might even have time to read it again before I send it. Spell check? Nah.
