Take control of the question:
Establish clear parameters for what you will include/exclude, acknowledge possible parts of the answer then rephrase to establish boundaries for the answer.
Acknowledge big names, theories, etc so you can’t be accused of having overlooked something, someone important. Explain why/how these theorist’s work is &emdash; while still important &emdash; less relevant to the direction you wish to take.
Outline the course of the paper (in advance is recommended).
Rest well the day before.
