My son had Mr. Kao as his math teacher back in 7th grade in a small group class, and he continued with him into 8th grade. Even in a group setting, Mr. Kao did an amazing job helping the kids truly understand Common Core concepts. He's patient, organized, and clearly very experienced with middle school math. In 8th grade, there weren't enough students to open a group class, but we still remember how much my son improved during the year he was with him. One thing I really appreciate about Mr. Kao is that he understands students with attention challenges. My son has ADHD, and Mr. Kao picked up on his learning style right away. He quickly identified where my son was struggling and used the right strategies to help him catch up. His patience and teaching techniques made a huge difference, and my son's confidence grew a lot because of him. Now that my son is in 10th grade, he actually asked to go back to Mr. Kao again. This time we're doing one-on-one lessons because we know he learns best with Mr. Kao's guidance. We're truly grateful for everything he's done. Mr. Kao is a caring, skilled, and reliable teacher who really knows how to reach his students. Highly recommended. read more

I heard good words about Andy from a friend just two weeks bf the final. My son's precal grade was tumbled in a high B at that time. Even worse he missed the whole last unit class due to AP exams. That left him very little chance to bump to an A unless he can do extremely well on his last unit test and the final exam. Since my son is new to Andy, Andy spend time to communicate with me about my son's background. He asked all possible materials(syllabus, my son's gradebook, homework etc) to identify a plan. Since lack of time, he picked the most difficult chapters in the last unit to teach. After working with him, my son got a 104 out of 105 in his last unit test, the highest score my son ever gets. He even answered right on the bonus question. My son was encouraged by the result. For the final exam preparation, since we have only less than a week left, Andy suggests to focus on two of his weakest units. Even in short of time, Andy doesn't rush. He still worked from the basic concepts and filled the gaps that he observed. Andy also tried to correct my son's working habit, asking him not to skip steps when he does problems in his class. That is one of my son's biggest reasons to miss math problem. The final exam was very hard but my son did much better than expected. He got a 92 and finally bumped his grade to an A! He was so excited. We really appreciate Andy's help. He is very experienced, honest, and encouraging. He knows very well on how to identify where need to be focus on. And he likes to clarify the fundamental concepts before going to solve individual problems. That improved my son's understanding of math. Andy's class is very effective. We will definitely continue having him for future math tutor. Highly recommended. read more

We found Andy online two weeks before my HS kid math final. And successfully bumped up 6% of the final grade. Andy's online classes are well prepare and not wasting any time. We will continue work with him. Highly recommended. read more

My child found Mr. Andy Kao as his math tutor just two weeks after he came to the United States. Andy is not only very familiar with the mathematics planning of middle and high schools in the school district, but also develops a tutoring plan for the special situation of my child. After four months of study, my kid easily took the state exam, passed the school district's Math Acceleration exam and successfully jumped to a higher level. I am very grateful to Andy for his dedication, and my kid will continue to take his class next semester. He will be happy to participate in the tutoring study of sciences in the future with Andy too. read more

Andy is a nice teacher who got into the bone of different student's needs. He spent extra hours to plan and adjust teaching strategies. We started the private class on MathII in 2017-2018. After that, my son could go directly to Algebra II in 9th grade. We are semi-homeschooling for High School. He taught my son one-on-one Chemistry once a week in 2018-2019. Couple weeks ago, my son passed the AP Chemistry Readiness Assessment. So again, he is well prepared to move on. Kudos to Andy!! Big thanks for your patience and love!! read more

Andy takes pride in his work and is very experienced in each subject that he teaches. Both of my children were his students and significantly benefit from his teaching. He is patient and methodical. Not only he cares about the progress made by the student, but he also would analyze the efficiency, prioritization, and quantity of each student's study habits and style. He would take the time to help each student improve on their study habits. He really feels vested with each student's success and offers a holistic approach to grade improvement. My family is grateful to have his help throughout the years. I highly recommend him to students in all types of learning stages. read more

When I started taking Chemistry Sat classes with Mr. Kao, I knew very little. He taught me everything I needed to know and gave me practice problems to check my understanding. When I took the actual Chem Sat test, I saw a 300+ increase from the scores on my first few practice tests. Mr. Kao helped me to build a strong foundation in chemistry so I feel more confident in the subject. read more

Andy is a great teacher and he helped my child to find more confidence and passion in Math, and also progress into an advanced level with less than a year. Andy is very detail-oriented and very systematic in his teaching methodology. He always pays good attention on my child's progress and helped to monitor the areas of strength and weakness. He helped my child to face and challenge the areas of weakness until they are no longer the soft spot. He is a nice teacher and my child always loves to come to him to ask questions. With one year's effort under Andy's teaching and advice, my child became lot more interest in Math and he did extremely well in the middle school placement tests. In addition, Andy also helped us to understand more about the roadmap of the school Math curriculum from elementary to middle school. Thank you Andy for your great effort and helps! read more

Mr. Kao is an extraordinarily good math teacher who is experienced and effective on spotting potential weak points from students and improving them. read more

My daughter began struggling in AP Biology in the middle of her first semester at school. It was hard for her to grasp all the details in depth since her teacher at school went through all the concepts pretty quickly. However, I am so lucky that I was able to find Andy Kao at the Apex Classroom. Andy is not only very knowledgable on the topic of biology but is also incredibly dedicated to each student. He voluntarily prepares each lesson in a diligent manner and often goes above and beyond to help. For example, he gives her frequent practice tests and will go overtime to make sure that he can go over the chapter fully. With his weekly tutoring lessons, my daughter soon got confident in Biology. She ended the year very well at school and got a perfect score on the SAT2 Biology thanks to Andy's help! read more

Mr. Andy saved my second semester as a freshman in Algebra 2 / Trig by helping me understand all the concepts until I reached an A. He also helped me through other math and science classes. His strategy of finding my weak areas and strengthening them built my strong math and science foundation. Mr. Andy's planning multiple steps ahead helped me schedule which standardized tests (APs and SAT 2s) to take and when to start studying for them. During class he would always answer my questions thoroughly, making sure that I understood the concept, and then asked me questions to test my understanding. He also gives examples that I can relate to (like in word problems) to make classes more interesting and engaging. His assessment of where I was and where I wanted to be prepared me for all the work I had to put in to achieve the results I wanted. I am very grateful for all his help and extensive knowledge. read more

Andy Kao, overall, is a very capable tutor who helped me in math and sciences. His organization and planning were key components to my success on my subject tests and in classes. During class sessions, he would pinpoint errors in my logic and identify weak areas of knowledge and then proceed to reinforce those areas by reviewing certain concepts, chapters, and even going onto the internet to play videos. With weekly classes and homework practice tests, I was able to achieve perfect scores on the SAT II Math, Chemistry, and Biology. Moreover, with Andy's expert help, I also was able to achieve 5's on AP Calculus, AP Biology, and AP Chemistry! Without his help, I definitely would not have been able to excel in my classes and on the tests. read more

As a student, I was doing okay in AP Chemistry and was quite concerned about my performance on an upcoming AP test. I signed up for Apex stressed about getting a 5 on the AP test as a sophomore, but after my test, I knew it was worth it. This class started off slowly, but it solidified the basics and strengthened my Chemistry skills. Thanks to this tutoring I achieved my goal of a 5 on the AP test. Apex is fantastic! read more
