Firstly, I hope you achieved your goal and managed to get an 80 this year? I recieved a 70 and 80 in year one, with the rest being 68s. In year two i've had an 84, 80, 77 and 74 and others mid 60's. If I'm honest, I still don't know how I do it and I feel like I'm just fluking my way through so far.... I just read, and I read outside of the suggested reading lists. I study the module learning outcomes and the grading criteria on the grading rubrics we get as a guide for what to include/the structure/building the argument. I make sure that I reference everything i say, and also make sure that I provide opposing opinions/thoughts - being critical is a key thing.
