We will do as many edits on each essay as is necessary, that is part of the fee. We also advise you how to fill out the 'brag' sheet, and those important but annoying questions for which they only give you 2 inches of space.
Students seem surprised by that, but they are only first drafts, and the idea is to get started.
Sometimes we ask you to gather information, do library research, or talk to people who are central to your essay. For example, many essay questions ask you to discuss a teacher or relative who was influential in your development. We often suggest talking to that person and asking specific questions. You'd be surprised how many students fail to do this, as obvious as it would seem. Very often, the critical phase is between the first and second draft.
