I'm sorry to hear that you don't have much time to do anything non-school related. My school work seems to be taking up a large portion of my life too.
I have been trying to get through Call of Duty World at War on the hardest setting as well. I believe it is called "Veteran" or something like that, so I kinda know how you feel. I got stuck at this one part that I just could get past for about 2 weeks of on and off play. Finally I broke through the lines, and got two checkpoints further, but alas, I am stuck again. The smoke grenades are worth crap and the snipers are deadly in that game.
Other than that, I'm not sure I can relate to you any more.
