Bizarre AQA AS Spanish results

Dear Forumers;
As background, I spend a month a year in Argentina, and my Spanish is very strong. However for my AS, I only got a B - our teacher send an email (below) saying our whole school's AS Spanish grades were very low. Did anyone else experience this?
"Looking at all the marks for unit 1 they are much lower than expected, and that includes all the UVI that decided to retake, which is a first, as they have always done better the second time round. I will therefore be asking for a remark for all of you and asking to get some scripts back too. With regards to the oral exam the examiner gave some dreadful marks to the UVI and was a little less horrible to you, so it will be more of an individual decision for you if you want that remarked too. As the school is dealing with priority remarks now we can wait until September to decide exactly what to do.
I do hope that despite the disappointment you're not feeling too down about your grades - there is definitely something odd going on with the marking this year but, having a look at how you did in comparison with the A2 retakes I'd say you've coped very well with a difficult paper and a harsh marking scheme."

Use paragraphs goddamit

And from what i've gathered on TSR forums, many people had problems with AS and A2 Spanish results

Many apologies; I wrote in a hurry!
That is (without schadenfreude) reassuring - at least it wasn't just us.
