timing is everything
Start on your essay early:
Give yourself time to think about your topics, and carefully consider the rationale behind each question or prompt.
Be clear. Be focused. Be organized: Make sure your essay follows a logical structure.
Think about the impression it creates on someone who doesn’t know you. Input from people you trust—counselors, teachers, friends, and relatives—can help you get different perspectives on how your essay affects those who read it.
Give yourself plenty of time for revisions: have at least three others proof read your essay.
Pay attention to rules of correct grammar and punctuation, and don’t forget to spell check.
