Gosh, I've got a home here.nearly forget......partially forget......completely forget.......but unwillngly ,that's the truth. Is it worth keeping eyes on one thing in the expense of overlooking others. This sort of situation reminds me of one iusse of GRE exam.(what a terrible test,compelling and absurd) over -pursuing a goal  amounts to little benefit for us. Students in China work day and night to attain a satisfying score, which is otherwise can't measure the ture ability of learning and the knowlege on exam papers has nothing to do with pragmatical experience. Some students cut whatever corners needed to pursue a fine mark and survive in current term and even cheat in the exam .Nonsense!!!not to say the students but the exam itself.
