William came highly recommended to us by friends whose children had participated in on-line classes during Covid and loved them. We reached out when our daughter was struggling with an advanced geometry class in 9th grade. When she started working with William, she was making Cs on the tests. Her final grade was an A. She found his tutoring to be clear, rigorous, and exciting. As parents, we found Computing Wisdom to be accessible, flexible, reasonably priced, and easy to work with.

We thank our lucky stars that we found Susanna as our math tutor. She has tutored both our 10 year old and 8 year old sons (separately) for the last two years, and the results are stunning. Thanks to her, both children are the top math students in their class (by a long shot) and more importantly, have developed a real passion for math. Susanna is an extraordinary teacher. Teaching math is very difficult, but Susanna is able to communicate complex concepts in a clear and understandable way. This is rare in the world of math. Beast Academy (the program they follow) is not easy and very sophisticated. But Susanna has an extraordinary talent for explaining complicated math concepts in a clear, digestible way that children can understand. Combine that with her endless patience and she is a rare find. Both of our children have a fluency in math concepts that is rarely seen in kids who are even much older. It is a joy to walk into our teacher's school conferences and hear the superlatives describing our children's math skills. That is solely due to Susanna and Computer Wisdom. We spent many years looking for a math program AND (equally importantly) teacher that would challenge our children and enhance their love of math. We feel very very grateful we found Susanna. As parents who were math majors, we did not have time to teach our children but know exactly what a truly effective, sophisticated math tutor/program should look like and this is it. This is not your standard "memorize this formula" or "do this algorithm" math. Rather, this program digs into the "why" math problems are solved this way and fully encompasses every aspect of a concept. Susanna is diligent in making sure our children understand each step of the process before continuing. Simply put, we are amazed by what talented mathematicians our children have become and the passion they have for math. And we owe it to Susanna and Computer Wisdom.

William Chau and Computing Wisdom exemplify the ideal in mathematical and logical instruction.  With their incredibly rigorous, deep and penetrating approach to math, our son was able to conquer an extremely sophisticated Algebra class in one summer and is now in the process of doing the same with Geometry.  More importantly, along the way, he has become an infinitely more conscientious student and worker.  Most importantly, he has become a truly analytical thinker.  While he has gained wonderful mathematical skills and views himself with confidence as a math scholar, even more remarkable is the fact that our son has learned how to attack problems of all sorts, construct a strategy to solve them and then present the evidence of their solution in unassailable fashion.  He owes that almost completely to William Chau and Computing Wisdom.

William has made a tremendous difference in my son's life! William uses a fantastic curriculum that challenges kids and makes them love math at the same time. My son is very passionate about mathematics and William was the ONLY person we were able to find in NYC who was willing to find the appropriate approach for an 7 year old. We have taken 3 years worth of courses so far. William focuses on skills and teaches problem solving methods so that kids can succeed in the future. It's not just about getting the right answer. After 3 years, my son has improved dramatically! Thanks to William and his individualized approach, my son will be taking pre-Calculus in 5th Grade! He has also placed nationally for the past 3 years in the Kangaroo Math Competition.

In addition, I have recommended William to friends and several have enrolled their kids. Even kids who did not like math started to enjoy it after seeing William!!! I can't say how impressed I am with Computing Wisdom. I have been recommending it to kids who are struggling and kids who are excelling in mathematics! You won't regret it!

I first had Mr. William tutored me in Algebra when he opened Computing Wisdom. It was a really challenging course, however, it made my math work from school looks really easy. When it was time for SHSAT, I went to Mr. William for preparing for the math section. Not only did I score pretty well on the SHSAT, but I also got into my specialized high school of choice, Brooklyn Technical High School. In my 10th grade, I took Mr. William's Geometry Course. Not only did I learn a lot from this course, but it was also the favorite course I attended there. Schools would just make us memorize equations and theorems, however, Mr. William truly made us understand the proofs of each and every theorem that was taught in the Geometry Course. During the summer of 2019, I took Mr. William's SAT Math course along with a course from another tutoring place that provided tutoring for both math and ELA. From what I experienced, I learned more from Computing Wisdom than the other tutoring place. Because of Mr. William's help, I scored a 790 on the math section of the SAT. As well, I was introduced to Mr. William's competition course Junior Math Olympiad--which isn't taught by the New York school system--and the math competition Purple Comet Math Meet. With these exposures, my math knowledge expanded even more. I truly recommend Computing Wisdom to students who would want to learn more in the math field because you're guaranteed excellent test results and more math knowledge than you would get from regular schools. 

Susanna has tutored our 3rd grade daughter (8-year old) for 1 year now and we could not be happier with the ongoing results.

Susanna is an extraordinary educator who takes the time to tailor an agenda to ensure our daughter fully masters the material before moving on to the next lesson; precisely what we were looking for in a math tutor.

In full transparency, the Beast Academy workbook is extremely challenging and would have impossible for us (both time and patience!) to teach our child ourselves since it requires a math professional to communicate the concepts properly and in the right academic setting.

Our 3rd grade daughter has already been introduced to introductory algebra, geometry, and even basic algorithms over the last 12 months under Susanna’s highly curated curriculum.

Another challenge for our daughter was ‘word problems’ containing multiple steps / concepts, which could be very frustrating for any student (at any age). Our daughter can now systemically attack the problem in a logical manner by showing her work step-by-step.

Susanna even taught Leela multiplication short-cuts and our 8-year old can now solve problems faster than her well-educated parents : ) For example, our daughter can multiply 73 x 8 or 85 x 85 in her head faster than my iPhone calculator!

Susanna is passionate, patient, and persistent and has developed a genuine connection with our quiet daughter; we couldn’t be more grateful.

Our daughter went from being a good student to top of her class in a matter of months and is now 2-3 years above grade level. Our very shy girl is exuding daily confidence in the classroom which is directly attributed to her Saturday morning classes with Susanna.

My wife & I were on the fence on adding yet another extracurricular activity (ie: reading tutor, chess, technology, tennis, swimming, etc) however we could not be happier in the investment and we have seen immediate returns.

We are so thrilled with the progress and passion that Susanna has instilled in our daughter, we would be happy to ‘pay it forward’ and speak to anyone in greater detail, just ask the staff of Computing Wisdom for our contact details.
