So basically, I have just had an awful exam an hour ago. But I needed additional paper as I accidentally missed some questions out by mistake.

The thing is, I forgot to put in that box on the main exam paper saying I have used additional paper, but this additional paper is clipped to my question paper.

If this has happened to anyone before please respond. I am unsure whether they will not mark this additional paper because I didn't put a 1 in that little box.
PLEASE HELP!!
