新加坡剑桥O水准考试（Singapore-Cambridge General Certificate of Education Ordinary Level Examinations，简称GCE ‘O’ Level），是由新加坡教育部MOE和新加坡考试与评鉴局SEAB共同主办的国家级统一考试，也是新加坡的中学生在4年中学教育结束后参加的考试。

考试一年举办一次，考生可以用获得的成绩为标准申请进入新加坡初级学院、理工学院或工艺教育学院。考试成绩也为英联邦各个国家所承认和接受，可用于申请海外英联邦国家的初级学院或是大学预备班。

贯穿新加坡中学四年教育的，仍是3+1的教学体系，三大模块数学知识和贯穿始终的数学过程思维训练，如下图所示。

数学过程思维这一环节最为关键的是思维技巧和策略思维方法。这部分内容是要求学生在掌握数学知识点的基础上，能活学活用，经过训练，学会常用的思维方法。
