The perception that no part of the essay writing process can be "systematized" (i.e. repeated over and over again) is flawed. It overlooks the fact that the structure of virtually every type of essay follows the same format. American high school English classes focus almost exclusively on the content of an essay. Since each essay assignment deals with new subject matter students assume that all essays are different. They dont realize that "topic" is an irrelevant factor. There is very little discussion about the format of a properly structured essay.
You can not deny the importance of admission essay because it enables the brilliant students to get through the universities of their choice. The evaluation of these essays become becomes very difficult for admission officers when there are number of students having same profile. Admission essay writing is an art. Mostly students can select the topic but in some institutions different topics assign to different students. It is very important to evaluate weather the student is eligible for getting admission or not.
