考试靠运气
有时候考试确实是要靠运气的，一直以来我运气是不错，没什么读书还能混到现在。
The key to this method is a good toss. Without a good toss, it is difficult to get a good spread for the grading curve. It is also important to get the toss correct on the first try. Exams can get crumpled if tossed too much. They begin to look as though the professor actually read them, and this is definitely to be avoided. Additional tosses are also inefficient and expend needless time and energy.
