Hello students,

My name is John and my curiosity is insatiable. Although I have completed a B.S. in mathematics, an M.S. in math education, and passed the national board exams for both massage therapy and civil engineering, I still endeavor to learn and grow at every opportunity. After teaching math at the university level for two years and competing on the Spartan Race Pro Team, I decided to give away all my possessions and buy a one-way ticket to Alaska. I found a bicycle in Anchorage and road it solo and unassisted across North America to New York City, where I now study philosophy and dance at Columbia University. I still ride the same bicycle to all my students' locations, rain or shine!

I chose tutoring over traditional classroom instruction because of the higher degree of freedom it allows me to tailor my lessons to individual students. The advantage of working in a one-on-one setting is that I can meet the student at his or her level of understanding and progress through the material in a logical way from that point. I believe in working at the student's pace and taking time to fill gaps in foundational knowledge. It is critical that the student constructs understanding through his/her own reasoning. Therefore, I typically don't lecture; I don’t allow my students to be passive listeners.

What distinguishes me most from other tutors is that I have no lesson plans when working with students (unless they ask me to write a personalized course for them, which I can do). I am trained as an inquiry-based teacher, which means, for each student, I create a progression of exercises that leads him/her along the path to understanding. Completing assignments and improving grades is obviously important, but I also place a high priority on developing my students’ ability and confidence in solving non-routine problems. While most beginning tutors are quick to demonstrate how much they know by doing the thinking for their students, I insist that my students complete assignments using their own critical thought. My mission is to provide the best possible tutoring service for my students, and ultimately to instill in them an appreciation of learning.

Please take a moment to read my reviews to see how other students find my teaching style. I look forward to working with you!

Elementary Math

When working with students, I try to target the source of misunderstanding and then lead them through their own series of logic to understand the process. My job is to clarify any ambiguity the student might encounter. To do this, I often create simpler problems for the students which illustrate a point and then generalize the point to the problem at hand. For example, a student might ask, "Does 4/52 plus 4/52 equal 8/104?" And I would respond by placing two measuring cups on the table and asking, "Does 1/3 cup plus 1/3 cup equal 2/6 cups?" This technique takes longer than simply dictating, "Add numerators and keep denominators the same." But I believe it is more meaningful to distill the idea down to an accessible form than to offer baseless formulas to memorize.

SAT Writing

SAT Writing

Looking for a professional to help bring up that SAT Writing score? I’m your guy. I know the SAT inside and out and I can assure you this test is learnable. I consider the Writing section to be the most learnable on the SAT. My fist score on this test was 590; my last score on the official SAT was 800. Most people approach this section confidently, but then stagger through as they realize their ears cannot always catch the mistakes. These questions are cleverly designed to trick the ears of native English speakers. I can do it too! Try to spot the error in this one: "The boy, together with his friends and accompanied by several highly renowned scholars, examine the document." This is an example of a subject-verb agreement error, a favorite of the test makers that you are guaranteed to see on the exam. One mantra to repeat on the Writing section is, "Get rid of the junk." Distill each clause into its subject, verb, and object by omitting the modifiers and appositives. "The boy examines the document." There really aren't many ways to trick the ear like this, so I will show you how to spot all the ones that may show up on the test. My course pack includes lessons on tense, faulty parallelisms, misplaced modifiers, pronouns, punctuation, subject-verb agreement, and other miscellaneous topics that you need to know. Please see my reviews to learn more about my teaching style and results: …………………. “Easy to work with” Always on time, and easy scheduling. My daughter met with John once a week at our local library for SAT prep. She enjoyed working with him and he was very motivating. She was able to improve her score by 400 points by giving her useful tips and challenging her to push through on the areas she struggled with. Highly recommended! Randi, 10 lessons with John “SAT Master” John’s SAT program was extremely beneficial in helping me prepare for the test. His lessons were tailored to my weaknesses and he even offered feedback for each of my essays during our sessions. During the eight weeks I worked with John, I was able to raise my score on practice tests from 1880 to 2160. I am much more confident going into the SAT now, and I know the improvement I have seen during this prep course will make a significant difference in my college application process.

Calculus,

Calculus

Calculus is my strongest and most popular subject. As a certified calculus teacher, I have worked with students from Calc I to Calc III at dozens of top prep schools and colleges including UC Berkeley, NYU, and Columbia University. Rather than simply offering rules and procedures to my students, I guide them through individually tailored exercises so they can construct their own understanding of concepts. My goal is for my students to understand calculus in the way that Newton and Leibniz did when they created it. What sets me apart from other tutors is that I completed a graduate degree in math education specifically to become a full-time professional tutor. I am not just familiar with the material for these courses; I have also spent thousands of hours studying how students most effectively learn math and have used that knowledge to develop an inquiry-based style of teaching. When searching for the right tutor, it is essential that you look at reviews to see evidence of positive results. Please take a moment to read a few of mine: ………………………………… “I Wholeheartedly Recommend John!” Over the summer of 2017, I was working full time at JPMorgan and decided to take accelerated math courses at Columbia University in Multivariable Calculus (Calculus III) and Linear Algebra. Within the 12 weeks, my goals were to learn as much and as quickly as possible, but I knew that it would be difficult juggling both demanding classes and a job. When I reached out to John about tutoring, I was nervous about completing the classes at the level I was looking to achieve. Both classes were extremely difficult, but John supported me every step of the way, helping me understand difficult concepts in a relatable way and encouraging me to push and believe in myself. I left the 12 weeks with an A in Multivariable Calculus and an A+ in Linear Algebra. However, the most notable thing about my experience with John wasn't that he helped me get the grades I was hoping to achieve. Throughout my time with him, he listened to my questions and concerns that extended beyond the academic classes. He listened to me share my thought and dreams of what I wanted to do with my life, becoming both a role model and confidant. After our sessions concluded, I was confident that I not only learned a great deal, but that I also gained a friend that I can count on. I only have the best things to say about John and wholeheartedly recommend him as a tutor. He's the best! Johnny, 9 lessons with John “You will not find a better Calculus Tutor” Our son was enrolled in Honors Calculus, a tough course at a very demanding San Francisco High School. Prior to working with John, our son did not really "get" calculus, had struggled with the course, and had been further set back because he had been sick repeatedly during the winter. Working with John, our son mastered the Calculus course work. He began to consistently get A's or A-'s on his tests and quizzes, and more importantly became comfortable with Calculus and has a much deeper understanding of the material. Our son really enjoyed working with John, and never resisted his tutor sessions. John is kind and very patient, yet still has high expectations, and our son responded extremely well to this balance. John is extremely diligent and very hard working and is an exceptionally accomplished person in his own right. Our son was motivated to work hard by John's good example. John was very professional in every aspect. He was extremely punctual and was not late even once. He was respectful and fair in determining hours worked and billed. In every aspect John was an excellent tutor and we cannot recommend him highly enough. Simon, 20 lessons with John “Professional, patient and incredibly helpful” John's tutoring style is the ultimate ideal of how math tutoring should be. I sought John out for help in Precalculus and Calculus I at Columbia University. After each session, I definitely felt that my knowledge and understanding of the subject material significantly increased, ultimately contributing to a very solid command of everything from algebra to integrals. Working with John not only helped me understand new course material, but also reinforced important fundamental concepts in mathematics. John's style is cool, focused and professional. If you are having trouble understanding a concept, he will patiently work with you from the ground up to make 100% sure that you have a command of the material. Compared to other math tutors I've had in the past, John is easily the best I have had so far. Working with him is one of the best decisions you can make and a very worthwhile investment.

SAT Math

Looking for a professional to help bring up that SAT Math score? I’m your guy. I know the SAT inside and out and I can assure you this test is learnable. That said, this is a strange math test, unlike anything you will encounter in the classroom. It's not enough to be good at math (and if you aren't, don't worry. There's hope!). I have two degrees in mathematics and I can tell you that nothing I have learned in class since 9th grade is helpful on the SAT. I scored a perfect 800 on the official SAT Math section in high school because I specifically studied "SAT Math", which is a totally different animal. Fortunately for you, the problems are not actually that complicated. The College Board can only test material that every high school junior in the country has seen. So this ties their hands considerably. Just like in the Writing section, the list of rules you need to know in the Math section is both finite and manageable. Mostly it boils down to the formulas you learned (in theory) back in algebra and geometry. Here's the snag- you probably won't have enough time to solve all the problems in the same way you would in your algebra and geometry classes. Some questions REQUIRE you to use the multiple choice answers or strategically make up values for particular variables. If you don't know this is coming or how to spot these types of questions, then you most likely won't figure it out in the minute you're given for each problem. I can show you how to move through this section quickly. Please see my reviews to learn more about my teaching style and results: …………………. “Easy to work with” Always on time, and easy scheduling.

So this ties their hands considerably. Just like in the Writing section, the list of rules you need to know in the Math section is both finite and manageable. Mostly it boils down to the formulas you learned (in theory) back in algebra and geometry. Here's the snag- you probably won't have enough time to solve all the problems in the same way you would in your algebra and geometry classes. Some questions REQUIRE you to use the multiple choice answers or strategically make up values for particular variables. If you don't know this is coming or how to spot these types of questions, then you most likely won't figure it out in the minute you're given for each problem. I can show you how to move through this section quickly. Please see my reviews to learn more about my teaching style and results: …………………. “Easy to work with” Always on time, and easy scheduling. My daughter met with John once a week at our local library for SAT prep. She enjoyed working with him and he was very motivating. She was able to improve her score by 400 points by giving her useful tips and challenging her to push through on the areas she struggled with. Highly recommended! Randi, 10 lessons with John “SAT Master” John’s SAT program was extremely beneficial in helping me prepare for the test. His lessons were tailored to my weaknesses and he even offered feedback for each of my essays during our sessions. During the eight weeks I worked with John, I was able to raise my score on practice tests from 1880 to 2160. I am much more confident going into the SAT now, and I know the improvement I have seen during this prep course will make a significant difference in my college application process.

SAT Writing

Looking for a professional to help bring up that SAT Writing score? I’m your guy. I know the SAT inside and out and I can assure you this test is learnable. I consider the Writing section to be the most learnable on the SAT. My fist score on this test was 590; my last score on the official SAT was 800. Most people approach this section confidently, but then stagger through as they realize their ears cannot always catch the mistakes. These questions are cleverly designed to trick the ears of native English speakers. I can do it too! Try to spot the error in this one: "The boy, together with his friends and accompanied by several highly renowned scholars, examine the document." This is an example of a subject-verb agreement error, a favorite of the test makers that you are guaranteed to see on the exam. One mantra to repeat on the Writing section is, "Get rid of the junk." Distill each clause into its subject, verb, and object by omitting the modifiers and appositives. "The boy examines the document." There really aren't many ways to trick the ear like this, so I will show you how to spot all the ones that may show up on the test. My course pack includes lessons on tense, faulty parallelisms, misplaced modifiers, pronouns, punctuation, subject-verb agreement, and other miscellaneous topics that you need to know.

SSAT

SSAT

Like the SAT, the SSAT is a very learnable test. I have seen my students improve their percentile scores by 30% and go on to some of the top 5 high schools in the US. The key to success in my experience is familiarity with the content and practice with the exams. The difficulty with this test is that the study guides and practice exams available tend to be of poor quality. I help my students navigate the ocean of study materials on the market, structure their studying, and understand the content tested.

Simply the BEST mathematics tutor!

After my daughter's first session with John, I asked her how it went, and she replied that she was finally able to understand five major concepts with vectors that she could not understand before the session. It just doesn't get better than this. John is an excellent tutor. We are so lucky to have found him!

Best Calculus Tutor in New York

I have worked with John for two years now on Calculus 1 through Calculus 4. He has a true command of the subject as well as the dedication to his students and their learning. Using creative examples like a piece of paper to represent a 3 dimensional plane or clear and descriptive definitions for vague concepts, John has not only helped me through the journey of upper level calculus, but has inspired a love of mathematics following our work. I surely would not be where I am without him, and cannot express my gratitude enough. If you are looking for an excellent tutor who will stick through to the end when things get hard, and push you through the toughest times you will encounter, look no further than John Y. And if you’re reading this John, thank you for everything.

A great tutor who can make difficult concepts understandable.

John does a great job in breaking down lesson concepts in a concise way. I used his services for both Precalculus and Calculus. Through guided practice that he is able to improvise on demand, you will gain a better understanding of the lesson concepts and able to work problem sets on your own. At my current school, the instructors tend to go heavy on the theory, leaving one to have to spend a lot of time in the math help room to actually understand the assigned problems. However, given the limited amount of tutors and large amount of students seeking help I found this wasn't this an efficient use of my time. I found it better to just use John from the beginning in my second class that I took with him. If you have underlying weaknesses from previous math classes, John will notice and correct it, leaving you able to focus on the new material. If you plan in advance, John is pretty flexible in the hours he can spend with you, giving you additional time to prepare for exams. In Precalculus in particular, I had no idea what was going on in the last three chapters before I contacted John. I still ended up with a B in a class that many just dropped at around the time I realized I needed to contact a tutor.

Insightful, Patient Math Tutor

I'm a student at Columbia University, and I really struggle with math. I knew I was struggling, but didn't really know where to begin or which concepts I was missing. John helped me figure out what to study, and was great at explaining the concepts. Topics covered include algebra, functions, geometry, and trigonometry. Despite John's high level of math knowledge and expertise, he patiently broke down each topic. We studied in a group with John, and he made sure the session was productive. I cannot recommend John highly enough. I could not have passed my class without his help.

Professional, patient and incredibly helpful

John's tutoring style is the ultimate ideal of how math tutoring should be. I sought John out for help in Precalculus and Calculus I at Columbia Univeristy. After each session, I definitely felt that my knowlage and understanding of the subject material significantly increased, ultimately contributing to a very solid command of everything from algebra to integrals. Working with John not only helped me understand new course material, but also reinforced important fundamental concepts in mathematics. John's style is cool, focused and professional. If you are having trouble understanding a concept, he will patiently work with you from the ground up to make 100% sure that you have a command of the material. Compared to other math tutors I've had in the past, John is easily the best I have had so far. Working with him is one of the best decisions you can make and a very worthwhile investment.

The most clarity in math I've ever had

I'm a Columbia University student with a weakness in math. I've had trouble all my life with it, and have been to countless tutors. John was the first tutor ever who made everything perfectly clear and ensured I knew exactly what he meant by quizzing me after each explanation. He was able to hone in on my weaknesses with warm-up questions and allowed me to set the pace of the session. I learned just under half a semester of Algebra 2 (around 24-28 hours of class time) in just 7 hours with John. He is clear, precise, professional, and would be the first I recommend to anyone who needs help in math.

Patient and Efficient

John tutored my 12 year old in 7th grade math over 4 sessions, specifically to help her find the gaps in her otherwise strong understanding of various concepts and fill them. He was punctual, easy to communicate with, patient and efficient at targeting those gaps. My daughter feels that the time was very well spent and she appreciated his calm demeanor.

Intuitive effective teacher

Good at quickly targeting areas I needed work in and provided useable strategies to apply. Taught me to approach problems logically to solve them more efficiently.

Great Tutor

I needed help before college with my calculus and John helped me a lot. He was very patient and very clear in his explanations, which was very important to me. He was always on time and very organised: during our second class he gave me a syllabus for our sessions, and had another a more detailed one for each individual lesson. I couldn't have asked for a better tutor to help me get ready for the London School of Economics.
