Marking the GCSE exams

For most my exams- Biology, chemistry, physics, geography, I ran out of space on the lines and would turn to the back of the page where it says “additional page if required , write the questions in the left hand margin” but for all the exams mentioned above, I finished the extra lines at the back, and was given a pink answer booklet. I entered the paper reference, exam date, candidate number and etc…
Will the examiners find the answer booklet and link it to my answers to the corresponding exam? Or could the booklet get lost? I did add all the information and question numbers but I’m worried since I was given an additional booklet that wasn’t part of the actual paper.
Will it be marked? Or could it potentially not be read??

i am surprised at how much you used the additional pages! i maxed used like 1 and half on a few, and not they won't get lost the additional pages and paper and all the questions and answer are scanned into the system and sent examiners, none of your work will be lost

Yes it should be scanned in with it!
But if you get your grades back and they seem kinda low for what you expected there is the tiniest possibility that something went wrong there so it is worth getting it remarked because then they have to find everything correlating with your candidate number so it should get marked then.
I went up a grade in comp sci (7 --> 8 despite being 4 marks off the boundary, they managed to find 5 marks).
And I went from an 8 to a 9 in physics by getting it remarked.
No harm in getting anything double checked if you feel something went wrong on their side.
Good luck 😊

Thank you for the reassurance! yes I do tend to write a little much for each answer (I don’t know when to stop)
