By doing the peer review for essay, I felt a little bit hassle to do that at the first time. However, the result turned out to be a good opportunity to learn new grammar and vocabulary. With reading classmate's essay, I can learn from them because I may do not know something that they know better than me as well as I can learn from their writing style. Nevertheless, I think I still need more practice to review other's essay because there are still many grammar and words that I am not familiar with.
