Help with OCR A level coursework

I researching for my coursework and I'm really struggling on my research and planning. My topic is the rise of Hitler and my question is "Assess the reasons for Hitler's successful rise to power in 1933", the arguments I'm using is the strength of the Nazi party, The failure of the Weimar government and economic factors. If anyone could give me tips on specifics arguments that I could study or how to structure the exam and paragraphs that would be great.
