I did not think you could do that for GCSE.
"Can I see my marked question paper before requesting a review of marking?
No. We've agreed with the other awarding organisations that we won't offer this service for your qualification.
This is to ensure that all students are offered the same services, regardless of which awarding organisation they completed their qualification with.
If you request a copy of your exam paper, it will be sent to your school or college after the review of marking deadline. If you think you might want to get the marking of your exam paper reviewed, you should discuss this with your teacher as they are in the best position to advise you.
