This is how I structure my essay for poetry:
Intro -
Para 1: AO1, AO2, AO4 (ONLY for core text) + AO3 Part 1&2 (comparison + critic/ interpretation - ONLY for core text)
Para 2: AO1, AO2, AO4 (ONLY for core text) + AO3 Part 2 (critic/ interpretation - ONLY for core text)
Para 3: AO1, AO2, AO4 (ONLY for core text) + AO3 Part 1(comparison)
Para 4: AO1, AO2, AO4 (ONLY for core text) + AO3 Part 2(critic/ interpretation - ONLY for core text)
Para 5: AO1, AO2, AO4 (ONLY for core text) + AO3 Part 1(comparison)
Conclusion -
Remember that comparison is only 5 marks out of 40 making it 13% so a 70:30 ratio is recommended
You do not need AO4 AND AO3 part 2 for the unseen poetry obviously - but if you know a little about that century then feel free to write about it - such as the 14th to 17th century was famous for Renaissance Literature and the Romantic Movement/ Romanticism was popular in the mid-late 19th century (1850's)
