All C&G centres have to follow strict procedures when returning written papers for marking.
They have a bag with all the candidates details, and a check sheet which needs to be competed before sealing the bag up with all the papers for return to C&G, this has to be done and returned the next working day.
It should be nearly impossible to send it back with competed papers missing, as the invigilation sheet also goes back, and it needs to be ticked to confirm that each paper is included by candidate name.
If you think that the centre has not sent your paper in for any reason, then once the chief examiners report has been published contact the centre and ask for your result, they can check it on the walled garden before the certs are issued. One of two things will happen once the chief examiners reports are published. C&G will send out the certs if you have passed to the centre who will send them on to you, or they will issue a notification of performance for candidates who have failed, so the centre can contact you to let you know. This should happen within about 42 days from taking the exam. The April 2395 results are out, but the certs haven't been issued yet, and the 2394 is still pending. So if you took the April 2395 exam, your centre can tell you your result.
