On Christmas eve,1984, I had just finished the exams and was afraid as the results of one of my major subjects had been very unsatisfactory.  I thought that I had only a 50% chance of passing.  Even if I failed this subject I would not need to repeat.  However I liked this subject very much and my results were bad because of my lazyness.  If I was forced to change to a minor in this subject I would be very unwilling.
