the essay should in total be about 40 pages, of which 16 pages of actual text and the rest having references, appendix, front page and so on. All references must be peer-reviewed. I two example essays for you to use as guides. I also have two course books that needs to be referenced at the data collection part, see the example essays for how they referenced the course books.
One of the example essays uses quantitative approach and the other uses qualitative, you can pick whatever approach you like.
