Discuss the rules-the seven tips-of proofreading. What is an effective process?

This essay should address the following seven points: 1. Read a document several times when proofreading; focus on different aspects each time.
2. Use tactics to avoid the errors and typos that your brain has been trained to ignore. They include reading the page backwards, reading out loud, and reading each word or sentence alone.
3. Have others proofread for you.
4. Try to wait a day or two after you have written the document before you proofread it.
5. Avoid proofreading large amounts of text in one sitting.
6. Focus carefully on what you are doing.
7. Take your time; don't rush proofreading.
