Gosh @Choisumwords I agree with you that her grades are great. And yay that she wants to take MFL (my subject). And her PGs are excellent.
I cannot believe the school is saying that and whoever it is should get themselves updated tbh.
Some unis take account of GCSE grades. Notably Oxford (and Cambridge, anecdotally to a lesser degree) and places like LSE and Imperial for popular courses, also Bristol, yes indeed also Edinburgh also subjects like medicine at a lot of unis. But in any case your DD's grades would be perfectly good for most of those (mate of DS's went to Cambridge with a 6 in Eng lang).
DD had a very similar grade profile (she had a mix of numbers and letters, 9s in her best subjects, mostly As, couple of 6s/Bs). She got offers from two of the unis your DD has been told not to list. This was for English and back in 2018. If anything, MFL is a lower tariff (bc it is so unpopular, sadly) and 2025 will see IMO lower offers or at any rate, more of them.
I would just mention btw that Lancaster has cut a lot of its MFL courses starting with 2026 entry. You can still study MFL there but the fact that some specific courses have been axed is not a great sign IMHO.
@WhereAreWeNow so six A stars, two As and a B? Yes I think Cambs will be OK with that! Those should be considered excellent grades. Remember that this year about 1200 students got all grade 9s out of more than 650,000.
Shocked at MFL study at Bristol with a C in the MFL tho @GreyCloudsLooming. I went there and a B (in the days before A star as well) was essential in the MFL studied.
