课程结构
每个模块的课程均包含20节LIVE课程，分为16节【日挑战】课程和4节【单元考核测验】复习课程（学生需要在复习课前进入配套的Pre-Recorded课程完成测验）。每节课程都将由2位 Stars 共同授课。在该模块的学习中，我们将讨论超过150个数学问题。
【日挑战课程】每节课中，学生都会学习解决全新的数学问题，老师们将通过启发式的教学引导和鼓励学生开创自己的解题方法。我们的LIVE课堂赞赏学生们提出自己的想法，鼓励每个学生和全班同学一起集思广益，构建各种不同的解题方法，更积极地参与数学发现。
【单元考核测验】包含20道数学问题，其中10题在正常难度范围内，而另外10题则非常具有挑战性。
学生评价
This is definitely one of the best math courses available. Prof. Loh explains the topics in a detailed way, and makes it fun.
This is an awesome course.
The video explanations are crystal clear and the challenges are fun. 5/5 would do again.
I think that this course was an excellent tool to “skim the surface” in the world of Combinatorics!
It tells every way to solve a problem and for problems, you get a turn to solve and get hints!
