I would advise any student who has not done paper writing before to seek proper guidance and do a lot of research on the same before settling down to do the writing. My physics teacher is a good professional essay writers but also interest the physics and teach the this subject while every year one book publish in market. This is because so many students are getting frustrated by the end results due to un quality work that they are presenting to the markers. If one has to do it by herself it is always good to have a mentor who will help you in doing the writing.
