Photocopies of scripts are available for AS and A2 examinations but not GCSE at present.
You may find it beneficial to obtain a copy of your script if you are thinking of resitting a module or if you are thinking of requesting a review of marking. Note that if you are applying for a priority review of marking after A2 results there will not be time for you to look at a photocopied script first.
At GCSE it is possible to request your original script to be returned to you, however if you do this you will not then be able to request a review of marking because of course you will have the script!
There are varying restrictions on requesting copies of coursework and controlled assessment. The examinations department will be able to advise on specific details.
