Thanks for the messages, everyone!
What's interesting is that my DD's letter tells her that her college will be confirmed in February. I'm not sure if that's the case with others? Certainly, many moons ago (so maybe not relevant), my college was confirmed at the time of offer, and the same with my son more recently. I'm guessing it's just because of the timing of the offer, but things do seem to be different all round this year...
