Hey, I have my history exam on Monday next week (AQA) and haven't started either. My teacher has made a load of summary sheets for all the topics containing all the relevant information which I am just going to read over them 5/6 times. What also helps is if you actually try and interest yourself in the topic your studying, which i find easy to do because I actually find history quite interesting.
Im in same position. If you have the textbook make notes and questions for your self and keep testing yourself on it. Try do atleast 2 sections from the textbook for 2 days and then do past paper exam questions. Are you also doing cold war exam on monday?
Guys be very careful because the Cold War exam papers have changed for the first time. All the syllabus is the same but the questions are worded differently to before so the past papers in Cold war are not as helpful as the Nazi and British Society ones, just a warning.
