This question already has an answer here:
I have been rejected by a particular university for MS two times now. I really want to get into it to work with a professor. I am thinking of emailing him to ask him what I can do to improve myself to become acceptable. I am trying to improve myself on various fronts that I can think of, so I would like ask him if I am on right path. I am a first generation student and I have no guide to ask, so he is that only one I can think of, to ask these questions. What would be the proper subject line for this? Right now I have "Help needed to improve myself" as subject. In the body, I will explain my situation and ask him if he could give me some of his time. What would be the proper way to proceed in asking for his help?
