ES1 - The How Useful Question. Probably the easiest out of them all. Once mastered, it is simple to receive full marks for these questions. Just remember ABCDLP:
A- Author
Is it written by an expert? Written by somebody with first hand experience or was personally involved? Remember that a British Government Source will usually be reliable.
B- Bias
Are we being told the full story? Or does it seem to favour only one side? Remember that Cartoons, Memoirs and Speeches can be biased too! Just think is the source being accurate?
C- Content
Give a general idea of what the source is telling you in a sentence or two. Basically is the information useful?
D- Date
Is it a Secondary Source? You could write: "Souce A is a secondary source and was written with the benefit of research or hindsight." Is it a Primary Source? You could write: "Source B is a primary source written at the time of Trench Warfare"
L- Limitation
Has the Author forgot to mention something in the source? Is there something wrong with the source?
P- Purpose
Basically, why did the author write the source? To inform the reader of something?

ES2 - Comparing Sources. Reasonably difficult but also once cracked can be really easy to nail!
  •  State whether or not the sources Agree or Disagree overall. 
  • Point out exactly what the sources agree/disagree about e.g. "Both sources A and B agree that the Suffragettes were extreme as source A mentions, 'letter bombs' and source B states, '...smashed glass windows'. 
  • Keep repeating this until you show all agreements/disagreements.
 ES3 - Explain the Authors Attitude
  •   State clearly in your own words the attitude of the Author (hated, agreed with etc.)
  • Use 2 or 3 small quotes from the source to justify that this is the attitude.
  • If you can, try to mention why the Author had this point of view
ES4 - How Fully Question/To What Extent Question

  •   State what the source is about e.g. Britain's Naval Expansion
  • Find the evidence to support this. (4 marks = 3 quotes, 5 marks = 4 quotes)
  • You MUST also supply at least one piece of evidence from your knowledge!
  • Your KU may point out that the source is limited.
ES5 - An Investigating Question
  •  Draw a table of evidence.(usually for and against) 
  • Try to get a total of 6 pieces of evidence.
  • 3 in one table, 3 in the other or 2 and 4. Never just one!
ES6 - Last Investigating Question

The question may ask: 'How far do you agree that immigration has been good for Britain?'

This is how to answer it:
  •  Say whether you agree or disagree with the question.
  • Use evidence from the Sources(table) to support what you have said.
  • For a balance, there must be at least 2 pieces of evidence which do not support your conclusion. Use phrases such as: 'However', 'On the other hand' etc. This gives the balance.
  • Give 3 pieces of evidence which must come from your own Knowledge.
  • The conclusion must begin: 'In conclusion...'
  • The conclusion must show both sides of the argument.
Note: Remember with an Essay to think: Introduction, Middle, and Conclusion or as I think:
  • Say what you are going to tell them.
  • Tell them 
  • Say what you have just said
