Hi,
So, I based all of my notes around the study design, and got an A+ in the exam. They will only ever ask you what they put in the study design. I spent about two weeks writing notes and memorising the information, then I spent most of my time in the weeks coming to the exam doing practise exams, first open book, then gradually closed book, to affirm what knowledge I do not have and improve my writing skills (getting it marked by the teacher).
If you know what's on the study design, you'll be fine. Any other knowledge is just extra -- but they don't expect you to know EVERYTHING in as much detail as you did for the SACs (except you need to know more detail for the extended response questions, but if you do past extended response practises you'll find that they ask similar questions).
This is an example of my study notes for History:
New Regime Challenges (in consolidating power)
The dissolution of the Constituent Assembly
Political opposition
The creation of the Sovnarkom
Land redistribution
The Treaty of Brest-Litovsk
State Capitalism
The Civil War
War Communism
The Red Terror
The Polish Soviet War
The 1921 Famine
The Kronstadt Revolt
New Economic Policy
And this is how detailed my notes were:
The Kronstadt Revolt
Cause
(Late Feb 1921) workers strikes
Martial law
War communism
Guirella fighters (Winter 1921) like Makhno & Antonov
Sent delegation Petro:
were not factories but the forced labour camps of tsarist times.
Effect
Revolt: (1 March 1921)
Thousands
Kronstadt Anchoirs Square
Kalinin failed speech
Endorsed demands Stepan Petrichenko only peasants, workers, socialists
Battle: (7 March 1921)
50,000 RA Soldiers
General Tuckachovsky
300 Delegates congress vs 16,000 sailors = the bloody field marshal Trotsky opened fire on revolutionary Kronstadt. ~ Stepan Petrichenko
End: (18 Dec 1921)
Retake naval base
2300 dead; thousands evaded to finland
Casualites
10,000 RA & 5,000 sailors
the beginning of a ghastly fratricide. ~ Victor Sergei
Significance
~ Lenin show respond to challenge w/ brutality
~ Accept current eco system needed to be replaced - NEP
As you can see, I did 'cause, effect, significance' for all key events -- it prepared me well.
