Opinion essay, which should have: the introduction, three body paragraphs and a conclusion paragraph. Since it should be an opinion essay, external sources are not necessary (unless you quote someone to support your opinion). Please, note that I am a student, so try to write from the student’s point of view, but despite that you have a full control of what you write about.
Also, please avoid using “I, we and you”, change it with something neutral and don’t make the essay too personal.
