Disappointment with MP2002

MP2002 is one of the worst paper I have ever sit for or perhaps the worst paper! During my ten days break after MP2004, I began to slipp into a holiday mood and so I studied MP2002 in a holiday mood and went to the examination hall in holiday mood. The result: Anti-holiday mood! Reasons for such a diaster for MP2002: I actually drew the velocity polygon on the acceleration polygon!! And I wasted time trying to figure it out and get demoralised. Then the following questions no mood to do liao and that's it. I only realize that I drew on the wrong polygon right before the examiner took my paper away! This is really an unpardonable mistake!! :@ :@ Arggg.... I hope to get a C, happy liao. I don't want to get D nor E nor big F.
