Very good, I like it very much, it’s the most fun class that I learn
NUUUUUUUUUUUUUUUUUUUUUUUUU I DONT WANT IT TO END. NO, NO, NO. I DON'T WANT TO LEAVE. I WANT TO STAY.
Wow, this math is so beautiful and elegant! This is my favorite class♥️ It is the most awesome and fun math class ever
I find it great! The teachers are amazing! They always explain. Also, they calmly point out mistakes and key points which are crucial in solving the problem.
it was fantastic
I love the lesson
My son was very happy and he told me that he had learnt a lot of new things and new ways of thinking. He got really engaged, although, before starting the course, he would say "I don't want to study during my vacations"... Thank you for your leadership and educational skills during the Module 0 course that my son took during the past 4 weeks.
it’s really a wonderful class
Its easy to follow. I like the videos
My daughter has enjoyed this class very much and is planning to take further classes with “LIVE” in the fall. Both of the instructors are doing an amazing job!
This is complicated but interesting at the same time
This is the coolest prof ever
