Rather odd that the Livy passage was one that is used (heavily adapted, but still used) in Latin Beyond GCSE, probably the most popular textbook for A level study... I thought the story looked a bit familiar!
The prose comp looked quite tricky, though - hope people doing that have got on okay.
Pliny questions were a gift; huge amounts to say on both of them, and I can't imagine anyone has studied or taught the dolphin letter without doing that sort of style question as practice. How were the Tacitus questions, for those who studied it?
