TESTIMONIALS
“Excellent SAT math tutor. My daughter was prepping for the SAT on her own but she wanted to improve her math from a baseline score of 610 in the PSAT . She worked with George 2x/week for 4 weeks before her test. She scored 780 in the SAT math portion. We didn’t think she can improve that much over a short period of time. George is very professional, he identified the gap that my daughter needed and explain the concepts to her thoroughly. I highly recommend George as an SAT tutor.”
~Parent of A.N., Fairfax H.S. 2023
“I am writing to share my daughter’s exceptional experience working with George to prepare for the ACT/SAT. George is a very clear and talented teacher who taught Caitlyn the math skills she was lacking, and strategies for problem solving. He was able to explain math in a way that made it easy for her to understand, retain and apply. The combination of his math knowledge and the gift of teaching resulted in a huge increase in her scores and performance from her PSAT to SAT and ACT. In addition, her work with him this summer filled in some gaps that she had along the way with covid and other areas of math that she never mastered. I’m certain this will help her in her current and future math classes. Thank you George! Caitlyn is grateful for support and help.”

“George Chiou has been a godsend. He helped my son with Honors Algebra 2, Honors Pre Cal and Honors Calculus. Math has not come easily to my son but with George’s help, he received A’s. My son also scored a 33 on his ACT. I don’t think this would have been possible without George. I’ve been a teacher for MCPS for the past 20 years. George is a gifted teacher with unlimited patience and a clear, concise way of delivering instruction. I highly recommend him.”
~Parent of R.M., Walt Whitman H.S. 2022
“George is the best math tutor I’ve had! With his help, I was able to increase my SAT math score 110 points. During every tutoring session, he was extremely thorough in explaining every concept and said it in a way that made sense. He was always patient and never got upset when I didn’t grasp the content immediately. George is truly a very qualified tutor who cares about each and every one of his students and their individual successes. I HIGHLY recommend!”
~K.P., James Madison H.S. 2021
“Short version: My son’s SAT score went from a 1320 to a 1590. The college acceptances and scholarship offers he’s been receiving these past few weeks have made us so thankful that we hired a tutor. Don’t look any further than George.
Long version: We hired George in the the Spring of my son’s sophomore year to help boost his math SAT score. He scored well on the reading section and planned to attend a liberal arts school, but needed to increase his math scores in order to become a more competitive college applicant. Wow! Not only did my “reading guy” far exceed his goal and end up with an 800 on his math SAT, he also developed great confidence in his math ability and now plans to pursue an engineering degree!
George was incredibly professional. He was punctual, friendly and always well prepared with new material. Our schedules were hectic and George’s flexibility made it easy to schedule tutoring sessions around sports and activities, altering days, times and location as needed.
Our concern with investing in a tutor was wondering whether our son would commit to doing the work, as his motivation in school tended to waver depending upon the subject and the instructor (call it selective laziness). And his mind was usually on baseball. We were amazed. He was incredibly receptive to George. Not only did he not gripe about going to tutoring, he seemed to look forward to the sessions and was diligent about completing George’s take home assignments. We never had to ride him as was often the case with school work, he just did it. We suspect he picked up on the fact that George knew he was capable of more and genuinely cared about his progress, and was inspired to meet George’s expectations. When my son learned of his perfect math score, his first text was to alert George. That says it all.”
