Never use this website. The quality is the worst in that no one has any experience of doing academic writing, as they can't even reference or cite the articles properly. Also, they say they have a money-back guarantee if they cannot achieve good marks, but they never give you back the money. So don't trust them.
One of my friends used this service and sadly failed the subject by paying the most expensive package. Still, they didn't give my friend back the money too.
