I think B-CC has made the on-site graduation permanent rather than doing it at DAR, which is way better from the perspective of getting there, etc. The graduation date should be announced in mid-February or early March at the latest, and ticket info comes out shortly after that’s done. 4 tickets are standard; if you want extra, there’s a form that gets circulated on the list serve and if you want extras, I’d fill it out immediately. Usually, the max people can additionally snag are 2-3.
