Happy Clients

Our happy students and parents!

My son is currently getting tutored by Ms. Yuna and she is one of the best tutors that I have encountered. She is very detailed, kind, and understanding of my child's needs. Also, every single time class ends, she sends homework and lesson reminders and makes sure that my child is doing his work. She is such an awesome teacher!

We are thankful for Yuna. Her professionalism and love for teaching helped my son keep up with math. My son did not like math before meeting Yuna. However, her engagement with my son pushed him to be interested in math. I do not think my son will ever fall in love with math, but I am confident that he will continue to be interested in math and keep up the excellent work. Thank you for everything!

James, Son in 4th Grade

Yuna has been an absolute delight to have as an Abacus and Math tutor. I have a six-year-old girl and an eight-year-old boy who love her. Her child development and teaching knowledge help my children engage and focus. My hope is for my children to have a strong foundation in abacus and math as they move up to the next grade. Abacus helped my children to calculate numbers precisely and fast. Overall, our family is happy with her tutoring. Thank you, Yuna!

Teddy was accommodating with my child and his group. He has a 1:1 tutor as well as group lessons with Yuna. Both of them are great and passionate about teaching. Also, they make each tutoring session exciting and enjoyable. I am confident that my child will have a solid foundation for the future. Thank you, Teddy and Yuna!

Sandy, Daughter in 6th grade

Algebra II has always been a struggle for me. I often felt lost, unable to grasp key concepts, and fell further behind in class.

My parents found Yuna through Learn.Abacus.Math and working with her have been a turning point. She explains concepts clearly and breaks down difficult problems step by step in a way that actually makes sense. When I’m stuck, she patiently works through it with me until I truly understand — not just memorize. Thanks to her, my confidence in Algebra II has grown significantly, and I can now tackle challenging problems on my own.

If you’re struggling with math at any level, I wholeheartedly recommend Yuna. She is patient, knowledgeable, and genuinely invested in her students’ success.

딸이 Mrs.Yuna 에게배운지 3달정도 되었는데. 한국 선생님인데 영어를 잘하셔서 아이와 두가지언어로 소통이 잘 되어요. 사고력 위주의 수업이라 아이가 정답만 찾는게 아니라 정답을 찾는 여러가지 방법을 알려주시는거 같아 매우 만족해요 ^^ 일단 아이가 이 수업가는걸 너무 좋아하구요 🥰. 선생님이 친절하시고 좋으셔서 잘 되셨음 하는 마음에 리뷰씁니다 :)
