<p>This is just a lame excuse.....</p>
<p>If the sheet were to expand....then entire sheet will expand .... not the part were you mark your answers....</p>
<p>I mean...in the first page of the answer sheet..you even mark your Name, registration number etc.....so if the sheets were to expand significantly ...even they could have been misinterpreted......But if that didnt happen....we can be sure that the answers weren't changed either!!!</p>
