My son has taken Algebra I, Geometry, Algebra II and Pre-Calculus with Professor Xu, we have to say Professor Xu is the best math teacher we have ever met. His courses are well-organized with a perfect pace for students to follow, and my child feels he made great progress without feeling overwhelmed. He said Professor Xu is very good at explaining hard math concepts in an way that can be easily understood by students.
Most importantly, the high quality of the handouts that Professor Xu personally Prepared is the biggest highlights of his courses. The course notes are very-structured, very comprehensive yet concise, and can even serve as a great alternative to textbooks. His course notes prepared my son very well for his CBE exams of Algebra 2 and my son got almost a perfect score on the exams.
We really appreciate Professor Xu and his team puts diligent effort into providing students with the best educational experience. Thank you Professor Xu and team!

Dr. Xu has an exceptional ability to explain concepts clearly and thoroughly. My daughter had previously taken Algebra with other teachers but continued to struggle with some foundational concepts from Pre-Algebra. I decided to enroll her in Dr. Xu’s Pre-Algebra class to help reinforce those basics—and it has truly been a game changer. Not only did she overcome many of her challenges, but her confidence in math has also grown significantly. I now plan to enroll her in Dr. Xu’s Algebra class as well, so she can review the material thoroughly and build a strong foundation for future coursework. Thank you, Dr. Xu, for your excellent curriculum and teaching approach.

Finding the right math teacher for my daughter has been a long and difficult journey, and we feel very fortunate to have found Professor Xu’s class. My daughter is currently taking his Pre-Algebra class, and we will definitely continue enrolling in his other courses. His teaching is clear, structured, and highly effective. Professor Xu and his team go above and beyond to ensure students truly grasp the material.
What truly sets this class apart is not just the quality of instruction, but the thoughtful and thorough approach to learning. The class is well-organized and well-paced, allowing students to progress steadily without feeling overwhelmed. One of the biggest highlights is the high-quality handouts that Professor Xu personally prepares. These handouts are concise yet comprehensive, exceptionally well-structured, and designed to reinforce key concepts. They enable students to preview lessons before class and solidify their understanding afterward, serving as an excellent alternative to textbooks.
Another standout feature is the careful review and correction of homework. Professor Xu and his team take the time to go through each assignment, ensuring students understand their mistakes and learn from them. Additionally, the weekly problem-solving class provides an invaluable opportunity for students to refine their thinking, revisit challenging problems, and deepen their understanding. This structured approach ensures that students don’t just memorize formulas but truly grasp mathematical reasoning and problem-solving strategies.
Since joining this class, my daughter has developed a much stronger foundation in math and genuinely enjoys learning with Professor Xu. She looks forward to his lessons every week. More than just learning formulas, she has gained critical problem-solving skills and a deeper appreciation for mathematical reasoning.
Another aspect I truly appreciate is the thoughtful encouragement Professor Xu and his team provide. In addition to rewarding students for their achievements, they include carefully selected inspirational quotes in their feedback, which I often use to motivate my daughter. These small yet meaningful touches make a big difference in fostering a positive learning experience.
We are beyond grateful for this class. If you’re looking for a rigorous, well-structured, and truly effective math program that strengthens skills, builds confidence, and nurtures a love for learning, I highly recommend Professor Xu’s courses. This class has made all the difference for us, and I only wish we had found it sooner!
Thank you, Professor Xu and your team, for your dedication and for making such a lasting impact on your students’ education!

Dr. Xu’s handouts are very comprehensive. After go over the materials during the class, I can understand the concepts deeper. The homework has a rotation on previous class contents, so that I have to review before completing the assignments. The best part is the cash incentives after midterm and final exams! It makes feel my huge achievement in math

Any comments? : We have attended two of Prof. Xu’s courses and truly appreciate his teaching approach. Despite being off-campus classes, Prof. Xu puts serious preparation and diligent effort into providing students with the best educational experience. One aspect that stands out is his lecture notes. They are clean and elegant, enabling students to learn the course materials without a textbook. More importantly, he teaches students how to take notes and complete homework. The notes serve as a template for homework and assignments.
Math is a rigorous discipline, where each formula and derivation is based on logic. Clear, step-by-step work is crucial in helping students develop good habits. Prof. Xu’s approach ensures that students build this essential skill.
Additionally, Prof. Xu consistently strives to maintain students’ interest in math. This is especially important for middle school students as they progress in their curriculum. He motivates students to develop the right mindset toward math. His assignments strike a good balance between the number of exercises and the time required to complete them, which is invaluable for this age group.
Thank you, Prof. Xu, and your team!

With a university professor’s profound math background, Professor Xu has a much wider vision of how the math knowledge are related and involved in middle school, high school, and college level math courses. Professor Xu teaches the algebra 2 concepts with bigger picture in mind, thus after taking his class, students not only master the new knowledge, but also make their previous knowledge more solid. Professor Xu has magically made his class easy to understand for middle school students by using well-crafted illustration, graphs, and detailed steps. Beyond that, he embeds some above level math problems for kids who welcome more challenge. Professor Xu emphasizes to his students the importance of preview, taking notes and review, and his homework recitation is a valuable bonus. They are great helpful for clearing any confusion and deepening the understanding. My son really likes Professor Xu’s class and benefits a lot from it. Thank you so much for delivering such high-quality classes to the community. From current student’s parent

Professor Xu has been engaging and interactive throughout the two courses I have taken with him. He voluntarily offers help and explains important concepts clearly and concisely, with well-drawn graphs. He’ll regularly stay up in the morning to check every student’s work, and will even use his own time to explain concepts in more detail. He actually cares about what you learn, and puts polls and practice questions sporadically through his lectures in order to provide some in-class practice. He always makes a point of reviewing what each class has learned so that they can remember it, and overall he’s one of the best teachers I’ve ever had.

My daughter is taking grade 9 math at school. She is doing well at school, but we always feel that school didn’t teach enough math to the students. So we registered my daughter for two math courses with Dr. Xu and we are so glad to see my daughter’s great improvement. Dr. Xu explained not only the concepts and principles, but also the strategies and skills to solve different types of problems in each chapter. He even correct student’s homeworks and exams and explained to students how to correct their mistakes. Thanks Dr. Xu, we feel much confident about my daughter’s math and we will continue taking precalculus and calculus courses with Dr. Xu. I would recommend Dr. Xu’s math class to every of my friend if they have a high school kid.

徐老師的筆記非常詳細，教學內容及講課都深入淺出，更有許多挑戰學生的思考题，訓練學生的思維。 數學課不再只是邏輯，更是藝術，徐老師經由上課，作業，挑戰題目及考試，將其完整的表達出來，非常喜歡。

Dr. Xu is the professor who reminds me my dad who is also a math professor in China. He always tries his best to explain the math clearly and my kids are so lucky to be able to join his classes. My younger son is going to continue to join whenever there is class available to his level. Thank you Dr. Xu for your knowledge and also patience in teaching kids!

Eric enrolled in Dr. Xu’s Algebra 2 for the 2020 – 2021 school year. Eric feels the content covered is very thorough and the teaching method is detailed. With what he learned in Dr. Xu’s class, Eric will excel in school for the same class and fully ready for the next level.

Dr. Xu is the best ever teacher we had. Every class he spent his own extra extra extra time with students. It’s well worth your money. You pay $$ and he returns you $$$$$$ worth of knowledge.

My son participated Dr. Xu’s Algebra 2 class last summer. Initially I was not sure how well online course works, surprisingly I found it turned out very rewarding. Dr. Xu is the most diligent teacher I ever met. A few things he did exceptionally well. First, He prepared his own course notes and wrote neatly in colors neatly. Kids really like the personal feeling. Second he set up Q&A session to make sure students’ questions cleared before moving to next class. Third, last summer he spent time to correct each students’ assignments. My son participated CBE Algebra 2 afterwards and passed with almost perfect score. Even as a parent watching class from side occasionally, I enjoyed the class and wish I had a math teacher like Dr. Xu 🙂 Thank you! Dr. Xu.

Precaculas with Dr. Xu have been so worthwhile! He worked really hard with kids and he has an amazing way of breaking things down so that they are understandable. My daughter learned a lot from him.

Dr. Xu’s classes are some of the most excellent classes. His classes are interesting and I can grasp new concepts quickly in his class because of his detailed explanations. Dr. Xu’s classes are challenging but easy to understand. I have learned a lot of new material from his classes, and I can apply that knowledge in my school classes. I highly recommend him!
