Use the AP1 form to provide as much detail as possible
Filling in an AP1 form with as much detail as possible allows the candidate to draw the examiner's attention to particular issues they want addressed. The examiner must then reference each point raised by the candidate.
It takes time and effort, but if you do not complete an AP1 form, I believe your appeal is less likely to be successful.
Here are some pointers for completing the AP1:
(1) Request an AP1 form and leave it outside the viewing centre with a pen and note pad for making notes. (You are not allowed to complete the AP1 inside the centre).
(2) If you discover an error, take a photograph of it. (You are not allowed to take any notes inside the centre).
(3) If you are concerned that you may not remember why you marked a section as an error (especially if you have found a lot of them or your teacher has pointed it out), leave the centre to make a note and then return. Always record as much detail as possible.
(4) Do this as many times as necessary until you have worked through the entire paper.
(5) Return your paper to the organising superintendent.
(6) Transcribe your notes on the AP1 form in as much detail as possible and request that the AP1 form accompany the appeal.
