6. James’s grade point average puts him in the top third of the graduating class of college A. Nestor is in the top tenth of the same class. Elizabeth had the same grade point average as Nestor. Nancy has a lower grade point average than Elizabeth.

I saw the following explanation and I wonder why "前十分之一的成績當然比前三分之一的好".

"in the top third of the class", 應該是前三分之一, 類似的, "in the top tenth of the class"是前十分之一... 前十分之一的成績當然比前三分之一的好

比如1～100名

top 10：1～10

前1/3：1～33

top10的gpa肯定比前1/3 强

in the top third of 很少见，是前1/3?

 Now I see the question.

The above analysis is wrong. your question definately has merit.

In fact, except for C, there is no other good answer.

Nestor = Elizabeth > Nancy ;至于James和Nestor都可以确定的是，他们两个是前10，但是不能确定谁更高，也许Nestor比James高，也许也可能相反

这个题里唯一能确定的就是Nestor > Nancy。

总算看到题目了^_^
