Worried about university?

Someone at uni on my course is causing me some alarm and worry. Now I might just be getting paranoid and this person my be wrong about this person, but I really don’t like what he’s doing. He’s goes to all lecturers and talks and winches about his problems, all the time. When we have work to hand in. He’s says to lecturer we are handing it in for, oh sir, I had this, that and the over on, this deadline and that deadline, and this bad thing happened to me, etc, etc, all at the same time of this deadline. Almost trying to persuade the lecturer into being more sympathetic towards him when marking his work. Pretty much like he’s bribing the teacher into giving him a higher mark. What I’m worried about, is that this feeds the notion that he’s had it rough, so therefore he should get a higher mark, where as because I and other people the cl don’t brag to the world about our problems, (which we do have by the way!) we should get more scrutiny over our results. So, what I want to know is, does the lecturer mark your work on the basis of what you’ve done and how good it is, or can it be influenced by someone else’s situation? What do you think? Any advice helpful? Thanks.
