Exam

Sardar Gurbachan   Singh  is   appearing for   his  University final

  examination which consists of  Y/N type questions.

  He takes  his seat in the examination  hall, stares at  the question

  paper for five minutes,  and then in  a fit  of inspiration  takes his

  wallet out, removes a coin and starts tossing the coin and marking the

  answer sheet - Y for Heads and N for Tails.  Within half an hour he is

  all done whereas the rest of the class is sweating it out.



During the last few minutes, he is seen desperately throwing the coin,

swearing and sweating.

The invigilator, alarmed, approaches him and asks what is going on.



"Oye, I finished the exam in half and hour".  "But yaar", he says,

"I am rechecking my answers and am not able to tally them with what I

 wrote."
