谢楼主分享，刚去了看了介绍， Comp Sci是新的tutorial Style exercise模式， 就是边教学边练习吧？ 看了SAMPLES里样题应该是这个意思，今晚要试试。

我小孩看过CS书, 光看书效果，不如有练习巩固一下效果好。我们公校高中开始CS课，提前学的孩子都是自己弄。

Beestar's Tutorial Style Exercise

Unlike other subjects that kids study in school, computer science is new to most students. Beestar has designed its computer science programs specially in the step-by-step tutorial style so that every student can join and learn without prerequisites. Essential knowledge is clearly presented in the exercise first before students work on solving problems. Students have all they need to complete a program in Beestar and parents do not need to teach or look for textbooks for them.

Beestar presents computer concepts in a kids-friendly way that students can grasp the essential ideas without getting into too much technical detail, so they can progress smoothly without burdening. In fact, we intentionally present computer science topics with their context from scratch, so each topic is fairly independent and even students who join in the middle of the program can mostly fit in the flow and learn effectively.
