Remark or retake GCSEs?

I got my results today, and although I was okay with most of them, I’m really disappointed about a couple of my grades. I have gotten into sixth form, and I’m hoping to do Bio, Chem and Maths and thinking of Medicine or Dentistry in future. Do you think I should get these grades remarked, or would it be better to resit them?
History - 5 😭😭😭(I was one mark off a 6. Earlier I was predicted an 8 and in my February mocks I got a 9 but the most revision I’ve ever done for History is cramming the day of or the day before the exam, usually because I prioritise other subjects. I can only say it serves me right for not revising.)
English language - 6 🥲 (7 marks off a 7, I’m thinking I should retake because I’ve heard English Language plays a huge role in careers. Achieved an 8 in my mocks, but in the actual exam I barely finished half of both papers due to terrible timing…)
For reference, my other grades are:
8 - Business
8 - Mathematics
8 - Chemistry (separate)
8 - Physics (separate)
8 - Chinese Mandarin
9 - Biology (separate)
9 - English Literature
I’d really appreciate any honest feedback and advice…

History is probably worth getting remarks for, decent chance it raises your grade. I wouldn't bother with a remark though because it's not at all related to your actual options. English Language I agree is more important but ultimately universities won't care about it too much as long as you have a 6. It won't stop you from getting an Oxbridge interview. However it might be worth a retake because there isn't much "content" so you wouldn't really need to revise it, so you shouldn't lose that much time for your A-Levels, and if your main issue really was timing you should be able to get at least a 7 quite easily. Again you could get it remarked too but I doubt it will take you to a 7, so if you really want it you should probably just retake it eventually.
