Extended Essay Topics to Write About

Unlike traditional essays required from you to submit for classes, extended essays require more in-depth research and utilization of theories. To provide a high-quality extended essay, a student needs to devote sufficient time for the study of selected or assigned topic. As well as that, it is crucial to provide examples and illustrations and support all arguments and claims with relevant facts. Moreover, extended essay writing demands critical and analytical thinking and thorough topic evaluation. Some topics might as well require experimental research.

Each extended essay should comprise the following sections:

  • A cover page;
  • A one-page brief synopsis of the topic/ main essay idea (abstract);
  • Table of contents;
  • The body of the essay (reflecting on the chosen extended essay topics provided by your academic supervisor);
  • A reference page (or bibliography).

Upon completion, the essay should be sent for grading.
