all the hard work you have done in researching your topic and issue will come to fruition in your argumentative paper.
Once you feel you have got the final draft, try to put the paper aside, even for a few hours, and then read it again.
Did you address at least three aspects of the issue you chose?
Does each aspect have relevant and authoritative evidence in support of your point?
Have you included a view that is in opposition to your viewpoint, and have you answered that opposing view, pointing out its flaws in such a way as to refute it?
