Please write your paper in your own words. That is the only way I can evaluate your level of understanding. Quotes are rarely needed; if necessary, they should comprise less than 10% of a paper and must be properly cited.

I really appreciate the work all your amazing writers do to ensure that my papers are always delivered on time and always of the highest quality. I was at a crossroads last semester and I almost dropped out of school because of the many issues that were bombarding but I am glad a friend referred me to you guys. You came up big for me and continue to do so. I just wish I knew about your services earlier.
