I am sorry that I have not prepared substantially for the forthcoming exams, especially the professional courses. I thought I had adequate time and energy but as a matter of fact there were always kinds of trifles to tackle. Perhaps it is not better than the state of last year. What should I say? It depends on the final result. Maybe I am a bit anxious recently. Sometimes I am too confidential to deal with seveal issues at the same time... Perhaps I should overlook some and emphasize other...
