Exams = Power ..... how?

Our Optical Sensors professor discussed this topic shortly in today's (22.01.2010) lecture

Lets see what he has explained...

Exams = Power  (Exams are nothing but Power)

lets come with the definition of power in the physics..
Power is defined as the amount of work done in certain time
P = W / T

and Exams are defined as amount of information you write on the papers in the given time

in this way Power and Exams are correlated :-) :-)
