you know youre screwed when:
1 you start to wonder if you can see a wireframe of the face of the
people´s whos in front of you
2 it gets worse when you get the irresistible urge to pull some cvs on that face

3 you only think on that differential equation you cant solve and its probable that you find one similar on the exam...
4 anyone feel free to contunue the tread ...
