Hogree- i've been told NOT to structure Thatcher like that. A strong answer will talk about sources 1 and 2 together in each paragraph
E.g 'statement for idea in question' back up with evidence from source 1 and 2
Then a statement against with evidence from 1and 2
Dependent on the nature of the sources you may find your answer is more in favour one way and another but give counter argument with evidence from sources 1 and 2.
So for example
Para 1 - FOR question discussing both sources
Para 2- AGAINST question discussing both sources
Then 3/4 - either for and against or both for or both against dependent on source
Then conclusion
This got me a high B grade with linking my own knowledge in to boost me to an A xx
