Pplication letter to Warwick University

I am applying to Warwick University study abroad program from Koc University, Istanbul Turkey and they want an essay that says:

If you would like to take modules in the department of English & Comparative Literary Studies, please attach a short essay detailing your previous experience of studying literature in English and why you wish to undertake English modules at Honours level.

I am Senior at Koc Uni, studying English Language and Comparative Literature but i applied for History Department of Warwick University because there were no place left at English Department. However I have to take English courses to graduate. So, please write a sophisticated and qualified essay that explains it. Also, please try to impress the international office managers of Warwick and write an essay that makes them say Ok lets give these courses to her”.
