The University library was crammed with my final year colleagues, some of whom had apparently been revising there for the full academic year. I was yet to open a book, and with a gap of 28 years since we all graduated, I was certain that I would fail this new set of exams.

KH told me that some of the others, including JG, had a clear advantage over the rest of us because their tutors had set them work throughout the year. I was not so lucky. My only hope was to persuade Mr H to tell me what was on the exam.

However, I was not a complete failure. The University had conducted an analysis of the social media interactions between members of the year group and the poster pinned to the library walls showed that I had come out as the best-connected member of the group. I also won the “longest hair” prize.
