Andrew did an amazing job, which greatly exceeded my expectations! He caught over five-times the number of errors that I thought may have existed. I accepted nearly all of his proposed changes, and the few that I did not, I seriously considered. He had many ways to better word things, which greatly improved the clarity of my writing. He corrected many subject-verb agreement flaws, which I am weak at, and he separated compound sentences with commas, which I rarely forget. Andrew has an incredible eye for detail; for example, he even caught missing spaces within a couple formulas and tables. Andrew was familiar with the subject matter—economics—down to the technical level. For example, he knew that economists conventionally write price elasticities of demand as positive numbers, although they are technically negative numbers. As I did not mention this in my text, he knew it would confuse my readers, and he recommended I explain this technicality in more detail. I was very impressed! Andrew also gave advice on how to present graphs/equations more clearly, and he caught a few labeling errors between these and the body of the text, which is well beyond what traditional proofreaders do. These are only a few examples of how Andrew has improved my writing. I give Andrew five out of five stars—he is truly a master in his field. Without question, I will use PaperTrue’s services again, and I will recommend them to my friends, colleagues, and students. Thank you!
