先摘录官网的两段话
The Edexcel International GCSE from 2009 Mathematics A (4MA0) specification is based on the legacy Edexcel International GCSE from 2003 Mathematics (4400) specification.
The Edexcel International GCSE from 2009 Mathematics B (4MB0) specification is based on the legacy Edexcel O level Mathematics Syllabus B (7361) specification, where you will be able to access more past papers.
没错没错~ 看到区别了吧？ 考纲不一样，一个是IGCSE的考纲，一个是Olevel的考纲。
那么IGCES的考纲和Olevel的考纲有什么区别呢？
我们继续搜索...
get！Olevel是新加坡的Alevel，也就是数学B主要是为那边的学生准备的...而又搜到参加数学A考试为主流。
大概是这样吧...！大家还不清楚的话可以去看一看卷子~
