Would I need a title for my essay, something like "Scholarship Application For..." (the essay question is "Why should I deserve this scholarship?") ?
I would use the
title: subtitle format. For example:
The Mountain Road
Scholarship Application Essay by XXX YYYYI once read that the scholarship essay should be in letter format, with Dear Sir/Madam at the beginning,
You should write a cover letter covering (that's why it's called a "cover" letter) all of the application materials, including the essay. "Dear Sir/Madam... Please consider me... Please see the attached... Thank you in advanc... Sincerely,..."
Since my essay is 1 page and a half in length, should I print it on two separated A4 pages, or one 2-sided paper is good enough?
The norm is to use two pages, although environmental considerations say one.
Would I need to attach a confirmation declaring that I am the rightful author of this essay?
The cover letter will implicitly assert and affirm your authorship.
Good luck!
