Gcse Maths roughly estimated score

It Is NOT a pleasure to say that based on the unofficial mark scheme, I got :

Paper 1 : 56 /80

Paper 2 : 64/80

Paper 3 : 50-53/80 ( if they give me method marks lol)

So that is 170-174/240 so I mostly would have gotten a grade 7. Now my dumbass regrets choosing furthermaths so now I will be converting to a level history, geography, philosophy and possibly biology (if I get a grade 7)
