I currently contract with CEA University Groups Team having interned with them over the summer. I have run the EA St Andrews groups for ~2 years.
EAs inflect upwards with their intonation. I think this is used to signal uncertainty and epistemic humility. However, it's often excessive and highly noticeable to non-EAs; I saw my family for the first time in six weeks, having been in Trajan during this period, and they highlighted this change in my voice (with much mockery). I thought it might be worth noting for those that aren't aware : )
If you haven't had 80k advising before, that could be a great place to start!
