A remark is a separate request - asking for your script back without asking for a remark will not change your grade. If you want a review of marking, you can submit one but it is a separate request.
Well if there is no reason to change the grade, they wont' change it...
Having the script returned to you won't change the grade - I think you're actually talking about requesting a re-mark.
Is there a specific reason why you think a re-mark is warranted?
It's my Creative Writing paper, I wanted to order it back so that I could keep it but there were worries that they may review the mark or tally up the marks again to check if that grade matches up and currently, the anxiety that inspires perhaps isn't worth it. I was wondering if it was likely to happen, or if it would have any bearing at all anyway.
