How to structure History assignment

[curiosity]

My daughter has an essay for GCSE coursework to answer a question about the reliability of a source (an extract from a novel about evacuation). She seems to have all the right points, but what is the best way to structure her answer? e.g Is it best to discuss the reliability of it's provenance then the unreliability of it's provenance followed by the reliability of the content , then unreliability of the content or to discuss both aspects intermingled. Which would be a higher level of writing?

Many thanks

The best way is to mix them together
Im studying history at AS level and if she can link and compare parts of reliability and unreliability of both aspects shell get a much higher mark

My history teacher told us to write conclusion first, then the paragraphs that build up to it then intro last.

Works best with loose leaf format rather than exercise book!
