Hi, I'm also doing Russia and its rulers

for exam structure the thing that I was taught to do is for the interpretations 30 marker is to pick to main themes out of each interpretations (two threads from each extract) and use the structure:
INTRO - briefly outline what the two extracts say and how they're similar or different.
P1 - Extract 1, main theme, quote the extract to back up main theme, how does it show this? Use evidence to either back it up or to criticise it, how far does it agree with the question, then come to a small conclusion.
P2 - Extract 1, same thing as P1 but with different theme/thread.
P3 - Extract 2, main theme, quote the extract to back up main theme, how does it show this? Use evidence to either back it up or to criticise it, how far does it agree with the question, then come to a small conclusion.
P4 - Extract 2, same thing as P3 but with different theme/thread.
CONCLUSION - overall which extract is more convincing, small bit of reasoning to say why, then concluding point.
For the thematic Q you could do something like:
INTRO - briefly outline paras and reasoning
P1 - Main theme (could be agriculture, politics, religion, economy) TRY NOT TO DO CHRONOLOGICAL, EXAMINERS DON'T LIKE IT.
P2 & P3 - thematic again, you can just use the PEEL format (Point, evidence, explain, link) try to use as much specific evidence as you can.
CONCLUSION - which theme is more important/ do you agree with the Q - make sure to always link to the Q
Revision wise I recommend learning some of the content chronologically (do some timelines under the spec themes e.g methods of repression) but also try and learn a few specific stats for each theme - this is definitely the hardest part but unfortunately you will go down in marks if you have no specific evidence, so try to break it down and learn stats or dates that can apply to multiple themes.
I hope this helps, I'm also struggling too as it's one hell of a topic with, imo, WAY too much content!
Good luck with the exam, if you need anymore help feel free to ask me.
