IGCSE Chemistry remark?

I've just received my GCSE results and although I did fine I'm still slightly disappointed. In chemistry I was targeting an A yet I was 1 mark off an A and got a B. Should I bother getting it remarked or for £40 is it not worth it? I'm not taking chemistry next year but just wondering if I should still get it remarked?

I wanted 8 A*s but only managed 6 A*s, 2As and a B, is that still good?
