Hi Nathan, thanks for your question. To reach band 6 of the mark scheme it requires evidence of “deep understanding through a complex and nuanced approach to the material used.” Nuanced by definition looks at subtle changes in meaning so as far as your essays are concerned this is showing an examiner that you have the confidence over the scope of the topic, making synoptic links to other ideas of relevance and bringing it altogether so your essay has flow. This is definitely a skill that comes with practice and it is not obvious like using technical terms but is more in the feel of an answer that a student develops their line of argument, showing a depth of understanding in the topic that flows and comes together in a holistic manner. Sorry I cannot be clearer or more specific because the wording is very subjective, so you asked a great question! Hope this helps a little 🙂
