Should I get my English remarked

So I got my English results around June time and I got a D for English gcse . I looked up the grade boundaries for the 2016 paper and saw I was one mark off. I tell my English teacher I'm really tempted to just get it remarked get my C and not have to study it again but she tells me over the years she's seen people get papers remarked and it stayed the same. So my main questions are...
If I did get my English remarked do you think I'm likely to get that 1 extra mark to give me a C or should I not bother and just sit the exam again next year?

Is it true most of the time you just get the same grade because I really can't be asked to sit this again if I could just get it checked over?

And honestly in my situation is it worth getting it remarked? Any replies to my dilemma are deeply appreciated.

Definitely get it remarked. I remarked four of my GCSE's and two of them went up enough to change the grade.

Hi,You seem important on TSR. How long do GCSE raw marks stay on the schools system and can I ring up the exam board and ask for my raw mark?

I think you have to ask your tutor if you can get it remarked and then take it from there.

How long do the raw marks stay on school computer system?
