Mathematics for a better future? Are you ready for that bright future?

Khoi helped me in AP calculus AB and BC. He's always available even if it was not scheduled via text. I can ask him about any problems that I am struggling with right away. I got both 5 on both AB and BC. Thanks a lot.

I had Khoi help in Differential equation and linear algebra. My professor at school did not explain the concents as well as Khoi did, and Khoi guided me through the problems with steps by steps instruction. Differential equation can be very difficult, but thanks to Khoi's help, I was able to understand and completed my assignments well. Thank you.

He helped me with precalculus class in a 8 week summer class. It was tough and we have to do online with zoom. But he explained the material well and wrote on the whiteboard screen of zoom to make the explanation much clearer. I would recommend him to any one at any age.

I had him help me with Business Calculus for a 8 week summer course. It was a tough class, but Khoi helped me understand the concept. We went over the materials using zoom and Khoi was able to explained it well. The hardest concept to get was the integral and he made sure I understand it. He is a great tutor, highly recommended.

He can also help with advanced level math. He helped me in advance calculus, which is real analysis. It is the very first advanced level course of math, which I struggled and was looking for help. He is always available. We have to run through many tutors because they could not help me with the materials. Khoi understands the subject well and it boosted my study. I can move with my other advance math courses cause I have a strong background now.

He so calm and relax. No matter how dumb the question is. He always answer with a smile.

He helps me understand concepts in trigonometry such as sine, cosine, the unit circles. His method is to the point and hilarious. I could remember the formulas with his tricks.

He helps me pass my AP Calculus with a 5. I was struggling with the integral and the volume generated by revolving, but he makes sure I understand the difference between the x and the y revolution. Thanks.

Khois understanding of math and his patience makes him a really great tutor! Always available for questions and helps whenever needed! Would recommend to anyone! If you need help ask for khoi!

I passed my CLEP in Algebra test thanks to him. He helped me understand the lessons from a book I'm using to review. Thank you. Definitely must recommend.

I was confused with left and right limits and the continuity. His explanation makes it super clear and easy to remember. I would recommend him to my friends.

He cares about your progress and works with you to make sure you completely understand the assignments, the methods to work on specific types of questions.

Very knowledgeable and patient! I would recommend him to anyone at any age as a tutor!

He’s very passionate about what he does and is probably the best private tutor I ever had . I’m learning a lot from him and without he’s help I would be able to pass my class.

He listens to his student and guide his student step by step. Highly recommended.

He listens and work with me on what I need. I get to choose what I want to study.
