This is a change/development question, and because it is 8 marks you should spend 12 minutes on it. Aim for 3 distinct points in 3 separate paragraphs. In order to get the full 8 marks, you must link each paragraph together so that the examiner can see that you are connecting your points together to answer the question. My model answer summary would be;
Para 1 = "One of the ways in which Hitler changed the fortunes of the Nazi party was through improving party finances." Then back this up with evidence.. "HItler was able to secure funding from the anti-communist giants of the German Industry including Krupp, Bosch and Thyssen. Without financial support, parties rarely make a breakthough onto the international politcal stage, Hitler knew this and used his newly secured finances to transform his party."
Here's the link for Para 2; "Improvement in finances enabled Hitler to expand the SA and set up his own protection squad, the SS, in 1925." Then provide evidence to back this point up and use a finishing sentence to connect this point to the last paragraph.
