我觉得还是挺简单的吧。考察是高中以下的知识，不会太难。你想美国人出的数学题能有多难~~~

首先，你要熟悉下数学专有词汇。

然后可以拿OG的数学题目练练手，如果发现很多基本知识忘了，可以针对性的补充下数学公式和概念。

如果这两部都搞定了，再把OG的题目刷完，控制下时间联系，正确率达到90%考试就没有大问题了。

除了OG，建议结合PREP的数学做做，OG的题目总体来说还是偏简单。

A circular rim 28 inches in diameter rotates the same number of inches per second as a circular rim 35 inches in diameter. If the smaller rim makes x revolutions per second, how many revolutions per minute does the larger rim make in terms of x?

 A 48π/x

 B 75x

 C 48x

 D 24x

 E x/75
