Incorporate ideas from other lectures (I will send the lecture on Marxism and the lecture outline for International Political Systems and use what you see is suitable), use theorists and theories to analyse and explain your ideas (very important!), and be analytical.
Use lots of (reputable sources).

All facts, figures, tables, graphs, charts, quotations and paraphrasing should be appropriately referenced

All references should include pages numbers where relevant
