I'm doing:
Paper 1 - Development of a Dictatorship in Germany, Superpower Relations (the Cold War)
Paper 2 - USA, China
For Germany, I'm guessing that Hitler's rise to power will be a question, and for the Cold War maybe a question about the Korean War.
For the USA, something about the Red Scare or immigration since those topics haven't come up in the exams lately.
I have absolutely no clue for China - it's anyone's guess since the questions can be so varied.
