CLASS TESTS----FUNNY RISKS!!!

Our teachers feel that class tests can make us more strong in the subject , but the reality is not so . Even when internal assessment is going on , most of the students(us!!!) will not consider it as important .
Once we wrote a test on data structures ,( without even knowing the topics) .We wrote it by grasping some points , which we have hardly listened amidst our plays in the class room.Those 45-minutes were crucial ,since my prof. made a look on every others paper!!!
Oh! it was the day to give the answer sheets corrected(who asked for that-just the teachers waste their time and ink it seems) ,our benchers got the same mark -boundary marks only(40)!!! .But the girl sitting at the back got double the marks(80)!!! she was in cloud nine!!! what? we really got surprised but scolded her too(as she did not write anything more than us!!) . At that time ,my another friend have not yet received her paper ,we searched for it everywhere ,,,,,,,,at last we found it inside the sheets of the 80 -mark girl...........yes,,my prof has corrected both the sheets as one( how he not even differentiate the hand writing???--fool,fooly)!!
Now the 80 -mark ,oh pity girl!!!!
