His editing will include very constructive comments at the overall draft, paragraph, and sentence levels. His comments did help me a lot to further develop my personal statement. I also highly recommend him.

Very efficient! He offered me very useful comments on how to improve the structure and flow of the essay beyond grammar and sentences. Highly recommended. -Xueting
