1) Pinch yourself on the cheek while trying to study Linear Algebra/Statistics, to stay awake
2) Promote the World Cup spirit by going for a one hour break playing table football, until your wrist and muscle hurt, good workout
3) Groove along to Bee Gee's "Night Fever", showcasing your best dance moves, when trying to activate the motion sensored lights in the library. It's either you've been sitting still concentrating too long (I wished), or staying still SLEEPING for too long.
Eeks, less than 2 weeks left till exams....
