Proofreading is an important part of writing a scholarship essay, especially if you're applying for a foreign program. Run a spell check of your text and fix any error you might find. It is totally unprofessional to have grammatical and punctuation mistakes in a piece of work of this level. Make sure to always use a word thesaurus that you master, otherwise you'll get lost in terms and phrases that don’t fit good together. You’ll want your paragraphs to combine one with another like puzzle pieces. So make your finishing touches, paying extra attention to details.
