This class actually has me pay attention lol. I remember I started these classes after listening to an in-person Po-Shen Loh speech, and he said “all online math classes teach kids is how to alt tab as fast as you can”
Thank you so much, i love this class. Byeeeee!
Pretty hard actually but I enjoy it.
We so appreciate the extremely thorough feedback on how my son is doing in class. We’re delighted that the degree of challenge seems well-matched and that he is always eager to join you on Sunday nights. Thank you both for your wonderful and warm teaching, support and interactions with the class. We know he is getting so much out of this experience.
In class, I learned a lot of questions that I didn’t know before, and I have already understood a lot! Thank you very much, and I would like to express my sincere gratitude.
Thank you very much for the detailed feedback. It was gratifying to hear [my daughter] contributed proactively and constructively to the class. She certainly enjoyed the class. You did an amazing job making math fun and building students' passion.
Thank you I learned a lot from this class
I love how the chat is always alive
Your expertise and thoughtful approach are much appreciated. The points you raised were spot-on and have already helped us identify key aspects to focus on moving forward. I am confident that implementing your recommendations will greatly help my daughter's learning. Thank you once again for taking the time to provide such valuable feedback. Your support and guidance mean a lot to us.
