We got our results 3 weeks after we had done the paper. However, it might be different for you, depending when your teachers mark it and when it is moderated. I wouldn't worry about it too much though. You'll probably forget about it considering you have half term.
I got my results the other day. I got 33/50 (C). I'm disappointed with my results. I might consider retaking.
Hope you get the grade you want!
