If you are studying poetry with CCEA your examination will be 'open book'. This means you will have an unannotated copy of the poems and you will be asked to compare two poems from your chosen anthology.
If you are studying Docker you are studying the Identity anthology. The following is an example of the type of question you will get.
Docker by Seamus Heaney deals with conflicting identities. Look again at this poem, and at one other poem from the Identity anthology which also deals with the theme of conflicting identities.
With close reference to the ways each poet uses language, compare and contrast what the speakers in the poems say about conflicting identities.
You should include relevant contextual material.
It will be up to you to choose a poem that deals with the same theme.
You must read the question carefully to ensure you understand exactly what you are being asked about Identity as all the poems in the anthology differ in their approach and message.
For example, you could compare Docker on the theme of conflicting identities with:
Belfast Confetti by Ciaran Carson
Genetics by Sinead Morrissey
Catrin by Gillian Clarke
