You just need to find out what the teacher wants from you, all you need to do then is churn out essays in a formulaic, box-ticking way.
So.
- introduction (outline argument, set criteria, define bits of question)
- point 1 (mini-into, point, evidence, explanation, analysis, mini-conclusion)
- point 2 (mini-into, point, evidence, explanation, analysis, mini-conclusion)
- point 3 (mini-into, point, evidence, explanation, analysis, mini-conclusion)
- conclusion (mini-intro, state opposing argument, why it's good, then say why it's isn't, use your main argument, no new bits of info here)
Analysis should also contain a counterargument and why that counterargument isn't enough to change your opinion.
If your revise and do this, you're guaranteed top marks.
