It's hard for me to be exactly confident when comparing my 25-year-old GCSE grade C (or was it D?) in French to the current numerical grading system, but I think it's it's somewhere around the peaks of these graphs: https://ffteducationdatalab.org.uk/2024/04/languages-are-sti...

My grasp of French is so monumentally bad, that last time I tried to say "I can't speak French" in French, the French woman next to me didn't understand because I said it wrong.

My German is coming along OK, but only because I've been living in Berlin since late 2018.
