学生评价
this is so good it is not boring and very engaging
太棒了，内容我都能理解，而且学到了解决问题的新方法。
This course shows you all the tips and tricks to not only to algebra but much more. They break it up into little pieces so you don't have to do much time every day. And whenever you have free time, boom! You can work on some math. This is coming from a fifth grader.
AMAZING
这堂课进行得非常顺利。我能轻松跟上，而且老师们都很友好
非常棒，一切解释都非常明晰
It's really suitable for people who find math boring at first (just like me), this course really gives me the passion for learning and exploring math!
非常好且有趣！！！！！
