One highlight yesterday was the parent after making a speech about the many advantages state school pupils have in the Oxbridge process over her privately educated son, then informed me that the English Language A level my DD was taking really wasn't highly thought of. So that's DD written off then. I'd better tell her not to waste her time applying.
Still, another parent was shocked to discover that the D of E award her DC was striving towards would be ignored by Cambridge and wouldn't boost their chances of getting an interview. The admissions person was ever so sweet and said that other places may find it relevant.
Those parents with DC in the iGCSE letters system were worried that straight A*s would be looked at less favourably than straight grade 9s. I don't think they appreciated how rare they were (with the exception of a couple of our chums here).
