I tutor mainly on pre-calculus, calculus AB and BC.

It is an easy job to give the correct answers directly to students. I prefer something better than that. I guide them to find the correct answers by themselves. So when they are in the test or exam, they can solve any problems. I explain to them the concepts and knowledge requirements behind each of the exercises. What they are all about. How we should tackle the problems. How we are going to break down the big problem into some pieces and apply which techniques to solve them. Calculus is all about making plans and ready to use appropriate techniques and correct formulas. For example, to solve integration problems, we should know which types of the problems are. Is it trigonometry or algebra or rational functions? If it is a trigonometric function, what do we know about it? Do we know sin^2(x) + cos^2(x) = 1? It is too basic to apply directly to the problem. Then we need to know how to change or convert the basic formulas to something like cos2x = 2cos^2(x) - 1 or 2cos^2(x) = cos(2x) + 1. Then we could integrate it directly or integrate by parts.

In short, I am currently a Software Engineering graduate student at San Jose State University. I got the AMATYC award (American Mathematical Association of Two-Year Colleges). To me, tutoring calculus is one of my hobbies so I tutor students with passion.

Hope to see you soon!

Great Day!

Khoa is a great tutor for Pre-Calculus. He has a good approach to make sure the learning foundation is in place and was able to get my daughter caught up in her class. This is the first time we have used a tutor and are very happy we did.

Khoa is very knowledgeable, patient, and hard working. He taught AP Calculus for my daughter. Actually I found him at the end of the school year, just a few of days before the exams; I wish I could have worked with him from the beginning of the school year so that she would have had enough time to practice the math lessons while also managing the other subjects. Though it was a last minute idea, my daughter is still in a better position than she was before the tutoring. I was really happy to find him. I would highly recommend this tutor at any time. I will definitely look forward to working with him again in the future. I hope he teaches all the other subjects as well!

Khoa was very thorough and dedicated in helping my daughter to understand every math concept & problem that she had trouble understanding. He gave lots of examples and allowed her to solve them. She is keeping all the notes and examples for future reference. Thanks Khoa!

He is excellent at tutoring in pre calculus and we are seeing results in soaring grades. He has patience and brains.

Approved subjects are in **bold**.

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.
