There is no greater educational tool available then a focused piece of research written to address a student's exact question. Not only will such a piece educate about the topic, it will provide useful insight into overlooked areas, intriguing arguments that had not been identified, concepts that were not even comprehended and elucidate definitions that the client believed had long eluded them.
Moreover, it will demonstrate not just a good writing style, but also an excellent writing style; it will enlighten the reader with its cohesive, well-structured approach and highlight many useful and often hard to find sources of reference for further investigation.
Perhaps even more importantly, over and above the assistance that any book, journal or tutor could ever provide, the help of a model answer service is specifically targeted to assist its clients (usually students) in the production of their own work, work that will be subject to the grading process.
Whilst the help of such companies has an honest use, it cannot be denied that such help is open to abuse but writers, who understand how strong the competition is for writing jobs may be tempted to write for such a company without first considering the ethical arguments against such a job.
The solution is to find a research company that firmly stands by the integrity of its service. A company that believes that the dishonest minority have never stopped any academic from publishing a book, journal or website through the fear that their work may be misused, and refuses to allow the same dishonest minority to deny the vast majority that want to learn and learn honestly.
The growth of the academic writing industry relies on your efforts in being selective about who you write for, and continuing to only serve honest companies, rejecting those that encourage cheating. Any writing company that sells the copyright of the work you produce, or places token disclaimers on their websites to mask their lack of integrity, cares nothing for the damage that promoting cheating will cause. Instead, find a company that actively encourages their clients to seek guidance on how or if they can use the work provided, and who stands by the policy that they will not serve anyone they suspect of dishonest intentions.
The media has also been guilty in recent years of attempting to brand any sort of internet education company as a facilitator of the downgrading or dumbing down of the academic process but not every writing company is the same. Academic Knowledge is an example of an honest writing company that cares about enforcing its policies and does everything possible to prevent the misuse of the service it provides.
