Thank you for the help, I took my time and ordered a 14 days long essay. It came much earlier, around 7 days after I ordered it. Oh, and it was good, of course. I like the writer who did that, will definitely use again.

What I received was great. I forgot to mention in the instructions field that I needed reference page and by default, there was 0 in the number of references. I was surprised to see a full-fledged reference page in my paper with relevant citations. Bravo!

When I first discovered this website I was hesitant on whether they will deliver a plag free paper. The support team reassured me of their plagiarism policy. In deed they kept their word as the paper I got was authentic and plagiarism free.
