虽然中国考生的基础教育，特别是在数学部分，在全世界范围内都是数一数二的，所以对于中国GRE考生来说，GRE数学部分与其他项目相比也相对比较低。但是如果备考GRE的同学对GRE数学部分掉以轻心，很有可能造成失分悲剧。TPO为备考GRE的同学们找到了英文原版GRE教程，希望对同学们有所帮助。
Set
A set is a collection of objects or things. Each object in a set a member or element of that set.Size of a set is the number of members in the set.
Example:
The set of even numbers between 2 and 10 is of size 5: {2,4,6,8,10}.
The set of primes between 2 and 10 is of size 4: {2,3,5,7}.
Remember:
Each member of set A belongs to A or is in the set A.
A set can not have repeating member: {1,3,1,2} is not a set.
Rearranging the order of the members does not change the set: {1,2,3}is same as {3,2,1}.
通过以上你的讲解和示例，希望能够帮助备考GRE的同学梳理数学基本概念，夯实基础。在GRE考试中的强项数学部分一举夺魁！
