So as to write a paper or assignment efficiently, you need to research properly in order to gather ideas and that can be time consuming.
While searching for my research I came across
www.degreepeer.com
Its completely free to use and has a wide collection of papers and presentations to help you with your research process.
They also allow users to ask questions on their website using their "Ask a Peer" service, in which other users that are online help you out by answering your queries.
My advice do try it
