Can I still score if I do badly in Pure Maths but good in Statistics?

I am never really good in Pure Maths but I can do Statistics pretty fine so I'm just wondering if I do like badly in Pure Maths 3 (maybe D) but really good in Statistics 2 (B or A), can I still get at least B? I'm really worried.

I got only C for my AS Maths but I really want to get at least B for overall (AS +A2), what grade do I need in A2 at least for this to happen?

Oh one more, will I be penalized or something like that if I don't answer questions in order? Today I sat for my A level Pure Maths 3 but I didn't answer it in order because I tend to go from easiest to hardest so I kinda did like 2,4,7,8,5 like that. Is that bad?

I'm doing CIE btw if that helps.

The pure maths component is worth more than the statistics part so while a good stats result helps to raise your grade it won't fully balance out a bad pure maths result.
If you don't resit AS what you need at A2 depends on whether was a really good C grade or a very low one. a good B at A2 may be enough if your C is high.
It's ok to do questions in any order you like,

I have been trying to learn how they actually add up all the marks to get the overall marks but I still don't get it. I know that they have this weighted percentage as in 60% for Pure Maths and 40% for Statistics but how exactly do they get the overall AS+A2? How do they even calculate the uniform mark?
