**Parents' testimonials**

"Among all remote learning lessons that (my daughter) takes now, I find your math lesson is the most organized and productive. You are always effective in communication, so parents know what kids are expected to do for the week. Thank you for continuing the math lesson online as soon as shelter in place is in order. "

"He said he’s learning the most from your class during this distance learning period :) It’s always great to hear that from the kids, because we all put in so much time and effort. "

**Students' Feedback**

"I learned a lot! once i began to learn from ms.wong i became better in school math and got good scores on the tests thanks to her teaching."

"Cool Math was very fun! Ms.Wong taught us a variety of math topics, that could be challenging at times, but she would always explain it again, and accept questions, so that we could master that subject. Not only did it really made me think outside the box, and push my brain to the limits, but it also helped me think critically about the world and look for solutions. -"
