I have ten years of tutoring experience. I've always been told I am good at explaining hard materials into easier and understandable concepts. Parents think that I have good patiences with students. I graduated from University of Washington with an Electrical Engineering degree. I started tutoring my friends and classmates in high school and found the passion in teaching. With having good feedback from the people I tutored, I've developed a stronger teaching skill as years go by. Being influenced by my mom, a high school teacher, I've comprehended her teaching skills while with my observations of my teacher and professors' lectures, therefore developed them into my own strength. I truly believe that there's a method in teaching, and I am confident that I can provide the help you will need. My tutoring experience includes Mandarin Chinese, math, Java, statistics, chemistry and physics.

****SAT/ACT/Standardized test Math Preparation****
I will evaluate my student's level of knowledge in math at the beginning of the lesson. Then I will come up a lesson plan based on the evaluation result and the preparation time we have till the test date. Different teaching methods will be applied to students accordingly since everyone learns in different ways. For example, for students having low confidence in math, I will first build their confidence up prior to showing them how to do difficult and complex problems. For students who are already strong in math and want to move to the next level or to get a perfect score, I will show them advanced math solving techniques, as well as how to tackle unfamiliar or never seen problems. In general, depending on students' math proficiency and the length of the prep time, I will choose to do a quick or a thorough comprehensive review to solidify their foundations in math, and work towards getting a decent or perfect score.

****Math****
I have the ability to walk my students through each problem step by step to improve their understandings in the process of solving math problems, as well as build their confidence up along the way. I am able to identify and reinforce any important concept my students are not familiar with, as well as help them to learn/refresh math solving techniques. In high school, I’ve scored a 5 on the AP Calculus BC test. In college, I’ve completed 6 math courses at the University of Washington, including the calculus series.

****Mandarin Chinese****
I am a native Chinese speaker from Taiwan. I can teach lessons in Northern accent(Standard Chinese) or Southern accent as your choice. I have the ability to teach you all levels of Mandarin Chinese including literature and ancient poetry. I am not only fluent in Mandarin Chinese, but also in English which help me teach more effectively. I provide a systematic way to help my student memorize vocabularies (Simplified & Traditional) as well as different teaching methods according to students' needs and level of proficiency.I believe that language isn't a hard subject to learn; however, having the environment is one of the key points. I can provide an all Chinese environment while tutoring with not just the language as well as the culture.

****Java****
I've tutored Java since college and I am a software developer for Android app as well as IOT products. Programming can be challenging when a logic is stuck and you have no idea where to start in order to solve it. That is the time when I jump in to help. No matter if you are taking a CS class or doing a project on your own, I can not only help you walk through and get the problem done but also help you think through the logic and algorithm. I once struggled with learning programming myself, so I know how to help someone who is stuck in the learning process of the language.

If you are interested in me being your tutor, don't hesitate in contacting me and we can talk more into details.

Great tutor!

My daughter has had Math lessons from Charles a few times now and will continue till next SAT for sure. He is very responsive and organized. That's my impression, and my daughter who takes the lessons says that he's good and she feels better now because she has a math expert helping her regaining math concepts. Thank you, Charles!

Roja, 8 lessons with Charles Chiaho

Knowledgeable tutor

Charles held a 2nd tutoring session with my son on math. My son told me afterwards that Charles had taught him some formula memorization tricks that helped him got over some hurdles a little bit. The next day, when he came back from school, he proudly said he used the tricks to help other classmates who had similar difficulty in that math area. Considering that math is my son's weakest subject, the tutoring does bump up my son's confidence in the subject matter, even a little at a time is worthwhile. Thank you, Charles!

Grace, 10 lessons with Charles Chiaho

Knowledgeable and patient tutor.

Charles is able to communicate with teenagers at a level they relate to. He doesn't overtalk; he gives just the right amount of information. He seems to have a good grasp on the SAT and ACT math sections and shares his insight well.

Janelle, 8 lessons with Charles Chiaho

consistent help

Charles has been tutoring my daughter for about two months. He always shows up on time and is able to explain concepts so my daughter understands. They go over problems and he is able to share the best way to approach the problem. Totally worth the price.

Polly, 23 lessons with Charles Chiaho

Great Tutor!

Charles is well versed in his Math tutoring skills and is also patient with his students. He make sure that Jocelyn knows the concept in solving a problem. He explained how to do the right calculation if Jocelyn didn't get the correct answer the first time.

Algebra 2

This was a very helpful session! Charles explained the material in a way that was easy to understand and my son now “gets it”! Thank you! We will definitely use Charles again for more help when it’s needed.

Algebra 1 Tutor

We asked Charles to help my with reviewing work to prepare for a test. He was patient had a great teaching style and left my son feeling prepared to take his test. I would definitely recommend using him.

Ryan, 1 lesson with Charles Chiaho

Works well at explaining and working through math

We hired Charles late for ACT math prep but he had several suggestions for us to work on. He was able to go through many examples of problems, working patiently to explain concepts and strategies for completing the math section. He was accomodating and flexible in scheduling lessons. My son feels comfortable and feels like he cemented some weaker concepts as well as strengthened ones he knew.

Tracy, 6 lessons with Charles Chiaho

Very helpful towards getting ready for the SAT

My daughter feels more confident in retaking the SAT math section again. Charles is knowledgeable and helpful. He explains things very well. He also gave my daughter extra practice problems to work with along with the going thru the Khan system. Charles is very nice person to work with.
