I think the most important thing you need to know is the structure of answering the question. You have to identify, describe, explain and analyse depending on the question. For example if it says describe two features of.... there is no point explaining. You would just be wasting time that you don’t really have in the exam. My teacher always taught us for describe always put “this is because...” for explain, “this means that... this shows us that.... this tells us that...” and for analyse it’s “some historians may argue that” and put a point that contradicts your identify. For the how far do you agree questions have an introduction, 2 for paragraphs and one against the statement or 2 against and 1 for. Always start the how far do you agree question with “ it is a compelling argument to suggest that.... it is a stronger argument to suggest that...” and a conclusion. Trust me on these point I got a 9 in my mocks and now I’m waiting on hopefully a very good grade in history.
I did American west, Elizabethan England, Medicine through time and Weimer and Nazi Germany.
And I revised using flash cards.
Good luck!
