“Hey-Sung prepared my oldest daughter for the SAT Math 2 and the ACT last year as she was applying to Ivy League universities. Hey-Sung prepared her to the very best.

From her deep knowledge of the material, to her passionate teaching methodology, from her multi-year experience in dealing with multi-aged kids, to her friendly and funny and very communicative personality, she is nothing short of an exemplary teacher.

Thank you Hey-Sung for all your hard and very effective work!! You left a very special mark in the heart and mind of my daughter.”

“Hey-Sung is hands down the absolute most exceptional tutor our family has ever worked with. My son has been tutored for several years with Hey-Sung for advanced math classes and most recently for Sat prep. Beyond the SAT result which was nearly a perfect score she is clear, organized and caring.

She has a gift of being able to hone in on subtle weaknesses and gives extra problems on areas where extra practice is needed. She is extremely familiar with the material and has a very logical approach while also offering strategy for complex problems.

In summary, Hey-Sung is an absolutely outstanding tutor. She is great for test prep and has an amazing ability to clarify material, teach and convey. Highly recommend!!”

“Self-reliance. Confidence. Success. These are the three words I would use to describe Hey-Sung’s approach. My 8th grade daughter started working with Hey Sung last year. After relocating from CA, she began struggling in her math class. Hey Sung worked with her to build up her foundation, strengthen her skills, and build her confidence. She is now in Math Honors, getting an A. Hey Sung is currently working with my 6th grade son. In the last 4 weeks, his grades have steadily improved, along with his confidence. If you are looking for a tutor, I highly recommend Hey Sung. She is earnest and passionate about teaching. As a parent, I also appreciate her sensitivity to the individual’s learning style.”

“Hey-Sung is a wonderful tutor. She is exceptionally smart, knows the curriculum well, and has outstanding teaching skills. My 14 year old daughter really enjoys working with Hey-Sung because of her relatable personality and the way she makes math understandable.”

Hey-Sung tutored two of my sons for classwork and the SAT. She does a wonderful way of honing in on a student’s baseline grasp of mathematical concepts. Starting there, she builds within the student a level of understanding that allows him/her to tackle the material and master the work. With one my sons, she said with a little more time and effort, he could reach 700 on the math SAT. She put the time in with him and he hit the number!! We were thrilled!!!”

“Communicative teacher to student and parents, with a good sense of humor. Our son questioned working with a tutor, but after meeting with her she won him over…he now does not like to miss his time with her. Excellent choice for us and our son.”

“Hey-Sung has helped two of my children navigate upper level middle school and high school math classes. She has provided consistent guidance and positive support for both boys. She has made herself available for extra sessions. When transportation and timing have been an issue, she has worked with my older son by skype. Hey-Sung really takes an interest in how they are doing and wants to help them succeed. Perhaps as invested in how they are doing as they are.”

I highly recommend Hey-Sung Han as a math tutor. My child has developed confidence and competence in math while working with Hey-Sung over the last three years. Hey-Sung is very knowledgeable, personable and punctual . Hey-Sung will keep me up to date on my child’s progress and will focus on specific areas of difficulty when she feels my child needs it. Her genuine desire to help my child achieve in math has been invaluable. My child looks forward to her math sessions. Thank you Hey-Sung!
