The internet has spawned many new businesses and academic writing is one of them. Anyone who needs to get a paper written just has to surf the internet to find academic writing help website. Most of the people running and managing these websites are based all over the world in places like India, Philippines, etc. their rates are quite nominal and that’s what lures students in seeking help from them.
There is only one absolutely guaranteed way of avoiding plagiarism and that’s by doing all the research and writing work yourself. Don’t trust a peer or any other form of help to do the paper for you. Conduct your own research and make notes. Taking proper notes is extremely important. You cannot quote an authority or from a previous paper without mentioning who it is that you are quoting, and from which paper, journal or book have you picked up the quote.
