this is so good it is not boring and very engaging

It’s great, I can understand and I am learning new ways of solving this question.

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

The class is going super smoothly and nicely. I can follow along easily and the teachers are all really nice.

It's good, everything make sense

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!

VERY GOOD AND INTERESTING!!!!!!
