Proofreading and editing services are necessary when you already have a draft or the whole paper completed and would like our writer to improve its content. Both these services will require you to upload the initial text since you are not paying for writing from scratch. Editing and proofreading are defined as changing the content of your draft, formatting the paper according to a particular formatting style, and proofreading the content. Editing and proofreading may cover a possible change of content of up to 25-30%.
