@hopelesschildren - ugh, what a pain! Yes, the ULEZ is the same as the Congestion Charge zone, however it is 24/7.
@WheelDecide - had DD1's re-marks back - all three papers, not one mark changed.
I'm not sure it would have had a bearing on her place (not Oxbridge); it was more a matter of pride.
I left DD1 to her own devices until yesterday evening, when I cracked and requested a Facetime chat. She's fine - has thrown herself into university life, and is really enjoying herself (but she's tired!). We are in Spain at the moment, which has been a welcome distraction, but it will be a much quieter house we go back to.
