-Letters were small and sometimes marker pens had less ink . -I love architecture practical series because it tested if we had studied the lectures every week . I do n't always study . In almost every lab , I was able to go through the lecture note and complete the lab successfully . That practical series made us sure that we would not miss any lecture . OOP practical sessions has no use other than wasting time without a proper day end objective . I think it was my main reason ( or at least my main not-motivation ) to become imperfect in OOP module . -Keep on the java course at the beginning . -Less examples in UML class diagrams . Some websites confused some definitions . Do some in-class UML class diagram .
