1) Is the global issue really present in both extracts?
2) Pay attention to the phrasing of your global issue - not too broad, not too specific - and make sure you meet the three requirements
3) Do you show knowledge and understanding of the global issue, extract and larger bodies of work?
4) What are you going to say about the style that has been used to present this global issue? What terminology are you going to use?
5) Are you analysing and evaluating or accidentally just making statements without discussing meaning and effect (= summary)?
6) Have you read, studied and applied all the rules in the syllabus and the documents on classroom?
7) Are YOU the owner of this piece? Are YOU the expert and can YOU defend and explain every choice you have made in your outline and do a proper analysis on the IO? This is YOUR work, YOUR idea, not the teacher's. The teacher just goes with what you have come up with and can only help you get the most out of it in the final 5 minutes.
