Proofreading is an essential part of writing, and it can be difficult to do it effectively. One trick that you can use to ensure that your proofreading is effective is to read your piece out loud. It is much easier to catch mistakes when you read the words aloud rather than silently. Additionally, you can also read your piece backwards sentence by sentence or phrase by phrase to get a better understanding of it. It can help you check for grammar and syntax mistakes.
Another useful trick is to take short breaks between periods of proofreading. When you read constantly for a long period of time, your brain can get tired, and you might not be able to concentrate as well. A break can refresh your mind so that you can look at your piece with fresh eyes.
Finally, it is also helpful to have someone else proofread your work. Knowing that someone else is looking at it can help you be more thorough in your own proofreading. Additionally, somebody else can also provide a fresh perspective and offer constructive criticism.
