I may be ignorant, but I hadn’t realised that the student had to send their CAGs to their chosen university themselves. Neither the school or the university requested this explicitly.
Yesterday, worried that my daughter was still in clearing, I asked her to ring her university and ask them whether she needed to send her CAG. They asked her to do so, and today they offered her a place.
In case anyone else is in the same situation, please send your CAG in immediately as clearing ends on Monday (at least it did for my daughter’s place)
