Does anyone know how long priority remarks on AQA normally take?

Hello! I've gotten into my insurance Bristol, which I'm honestly not disappointed with because it's a great uni, but missed my offer from my firm Birmingham due to getting a C in English instead of a B. I was 6 marks from the boundary so ordered a priority remark (covered by the department fortunately), but does anyone know how long these usually take on AQA? I'm worried that it won't get done by the 31st, and I won't be able to get my place at Birmingham. Also, is the subjectivity in marking usually high enough to go up 6 marks, or is that a bit of a jump? Thanks for any advice and I hope you all did well and are feeling happy with your current situation - whatever happens, it's not the end of the world even though it may feel like it
