I'm a Masters student and throughout my studies, I've bought many pre-written papers. I have used several companies but after comparing the quality of the papers I purchased one company seemed better than the others and chose to use them.
I will not recommend which company so as to comply with forum guidelines.
I usually buy 3 or 4 papers for each of my assignments as I find it really helpful. They give me the information I need and saves a lot of researching time as they provide the references with each paper so it makes a good article easily accessible.
As long as you use the papers as a guideline to write your own paper and do not copy from it, you are not plagiarising, it's merely another resource.
I believe reading a pre-written paper on the same topic as the one I am required to complete saves me around 50% of my time when researching and writing. I would recommend other students to use pre-written papers.
In fact, this was even recommended to me by my University Professor!
