She helped my daughter who is going to be in 9th grade next year get a good math score, Very impressed. My daughter used to be very lazy in math now is good grade in math and physics

Youya really helped my son (14 years) improve his math. He went from a C- in Geometry to a A- by the end of the year! She knows how to teach well, and I would recommend her for kids who are struggling in school.

She played a crucial role in my journey of learning math. When I asked her for help with my math project, she responded quickly and guided me step by step on how to build a regression equation in Excel. Her explanations were not only detailed and enthusiastic, but also incredibly patient. She never stayed on the surface—instead, she helped me understand the purpose and logic behind each step. Her way of teaching was so clear and simple that I was able to truly grasp the concepts. Thanks to her guidance, I successfully completed my project and received an A. Later, when I ran into problems while preparing for the final exam, I continued to reach out to her. As always, she patiently helped me, and in the end, I scored 90 on the final. I’m so grateful for everything she’s done for me.
