Yeah, it sort of went along with my 5 hour physics final.... 5 hours, no breaks... from 3 untill 8... No supper, no drinks, it was horrifying. and I still have a calc final thursday. Staring at mechanical simosoidal string waves, complex gravitational systems, energy/momentum conservation with thermal and audio dissipation, weird frictional kinematics problems involving cannons on trains going up hills into springs with an axel coefficient of friction and a wind resistance, and shm graphs, for hours on end is enough to drive anyone NUTS!
