I am a strong advocate of 'PETER' (point, evidence, technique, explain, reader response) paragraphs. They allow you to effectively tick all the boxes an AQA, Edexcel, OCR or any other examiner will be looking for if executed correctly.

If you are looking to go further and really impress the examiner, I advoate slightly deviating from this structure, adding more depth and exploring alternative viewpoints. I would hapily explain both the basic 'PETER' paragraph and how to take it one step further in a one on one tutorial.
