One mark of B, should I get paper remarked?

got my results today A in English language, B in Politics and C Philosophy

I got 109/200 in philosophy (AQA) and the boundary for a B is 110/200 so I was wondering if it would be worth it to get a remark for my peace of mind but my philosophy teacher did say a few months ago that philosophy marks don't typically change so idk

I did however get into my firm Birmingham so I'm happy either way!

would love some subject specific advice

You can always ask for your paper back to see if a review of marking would be worth it. However, if you got into your firm then you can question whether that would be worth the hassle.
