DS isn't applying to Oxbridge but I have been lurking on this thread for a while to see what you've been saying about other unis as early applicants.
In terms of whether unis are being more flexible this year we don't really know. For DS' course, Hull say 112 UCAS points and that's what they've offered him. Glasgow said AAB-BBB and they've offered him ABB, so in the middle of that range.
York is an interesting one. They say on their website AAA for ds' course. They've offered him AAB but for a different related course.
He is waiting to hear from his other two choices.
