As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
