这是我的第二此gmat

考试比上次要难. 但是这个其实有可能是取得高分的表现. 我觉得这次主要改进在于sentence correction. 太重要了. 因为一上来三道改错题, 如果错了很多, 那你的分数是不可能很好的.

“The most effective way for managers to assign work is to divide complex tasks into their simpler component parts. This way, each worker completes a small portion of the task but contributes to the whole.”

“Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its twenty-fifth birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.”

数学很搞,但是没有什么难度. 我记得的概率题:

1. 一种植物可有绿黄两种颜色, 可长成直叶和曲叶两种. 两个事件独立.

长成绿色概率x, 长成直叶概率1/4, 长成绿色和曲叶概率3/8. 求x

我选1/2

2. 求取出一只笔是defective 的概率:

(i) 好笔和坏笔之比 49:1

(ii) 100只笔, 好笔98只

我选B
