If you are a college or high-school student pondering over whether it is ethical and/or safe to use a writing service to complete your essay, assignment, thesis etc., you will find some useful information here. The moral part of the dilemma is entirely up to you to think of, but as for ensuring confidentiality and safety, here are a few tips for you.
It is a fact that most anti-plagiarism websites save a copy of the data they scan. This means that even if the paper you receive is original, if it is saved on one of these websites and when your professor uses the same, things can become uncomfortable for you. Make sure that there are no previous records of your paper online.
While many writing services providers have professionals, who have degrees and the requisite knowledge and skills to write your paper, there are other websites which are pretty unscrupulous in this regard.
The work given to you by the former will be of good quality, and carefully crafted in order to ensure that you receive a good grade. With the latter, you may end up receiving a paper that is of no use at all.
Paying for just a silly paper copied from Wikipedia and other such sources is certainly not the smart way to go about things in such a scenario.
Choose carefully, read reviews, and talk to the service representatives to make sure that the work you receive will be good enough to be submitted to your professor.
In case you are not satisfied with the paper you receive, you will want to have a back-up plan. Chances are, you will not have time enough to write the whole paper yourself, and besides, you would have already paid for the paper. Make sure that the writer will redo your work according to your specifications, till the paper is good enough to turn in.
Make sure you order your paper well in advance (this will also cost less, possibly saving you a lot of money), and that it is delivered to you quite a few days before the deadline.
Read through the paper, paraphrase it, and write it down in your own style. This is important because a professor who knows the way in which you express yourself will certainly be suspicious if you submit a paper that is entirely the work of someone else.
If you keep the tips listed above in mind, you will probably be safe using a writing service and will manage to get away with submitting a paper written by someone else. Make sure that you use such services only when there is no other option open to you. It is always best to do your own learning and assignments.
