John Z. passed a background check on 2/21/13. The check was ordered by John through First Advantage. For more information, please review the background check information page.

After sending a message to John, you will be able to order a new background check for $7.99. As part of your tutor selection process, we encourage you to run updated background checks. Please also review the safety tips for hiring tutors.

I instill a deep level of understanding of the material that will not only prepare the student for tests, but also be able to apply these concepts to real world problems and build upon this knowledge in future classes. I encourage multiple ways of solving problems and never judge the student. I blend in critical thinking skills and estimations. I often estimate seemingly difficult calculations and show how I got there, which causes students to stop relying on their calculator. I concentrate on improving the student's mental flexibility about how to apply the rules to the system. Once understood, you can apply this skill to most math and science problems. Above all else, I seek to encourage an understanding and appreciation for the material, sometimes with puns and jokes.

I prefer to talk about Physics, Chemistry, and Calculus as they are thoroughly interrelated; however, I often must strengthen the student's Algebra, Geometry, Trigonometry, or Precalculus in order to get the most out of Physics or Chemistry. I am more of an academic coach than a tutor. I am always available by phone or email for any questions. I will rarely just give the answer; I prefer to walk you toward the solution and assist you past your weak points. I am excellent at finding the piece of information or logic that allows everything to flow for you. I customize each lesson for the way you think. I relate the material to things you already understand and show how it is interconnected. I often make up examples using your hobbies and interests and can even show you how certain equations affected history or art. I try to be as efficient as possible with our time by taking personal notes and reflecting on what did or didn't work. After an adequate level of understanding is achieved, I focus on nuances in the material for speed on tests and implications to our daily lives that flow from taking the concepts to their natural conclusions. I enjoy seeing that moment when something the student was struggling with becomes easy. If you ever think you do not understand the material much better after one of our meetings, there is no charge.

I passed the rigorous 8 hour long Fundamentals of Engineering Exam(FE) which tested every math and science topic I offer and some. I have volunteered at St.Joseph-St. Thomas and Gonzaga schools helping students in math and science. I started tutoring Calculus, Physics Latin, and Chemistry in 2002. I am a Chemical Engineer who earned his masters from the Cooper Union for the Advancement of Science and Art. I also graduated from Regis High School in Manhattan. I have successfully tutored many students from schools such as Pace, NYU, Columbia, Stuyvesant, SI Tech, Xavier, LaGuardia, Murrow, Brooklyn Tech, Sacred Heart, St. Joseph Hill and many others in Physics, Calculus, SAT Math, Chemistry, Algebra, Geometry, Trigonometry, Pre-calculus, and Latin. I can show you the simplicity in what you formerly considered was madness like I have for so many.

Calculus is the math that Newton invented when he realized he needed stronger tools to solve Physics problems. I like how Calculus uses rather simple concepts to solve problems that would be nearly impossible using more classical techniques. After Calculus, I went on to study Multivariable Calculus and Differential Equations, two disciplines that build on Calculus and are extremely helpful to many professions, especially engineers. Over the years, I have helped many confused students realize that Calculus is much simpler than most of the math that they have seen before.


Chemical Engineers require a strong background in chemistry mostly to make sure that what you are doing won't explode. In my quest for my Masters in Chemical Engineering, I studied physical chemistry, organic chemistry, and took several labs applying those lessons. At first, chemistry can be really tough because it seems like there is always an exception to the rule, but once you begin to think like an atom, things get less electron cloudy. I can help you forgive your grievances with chemistry and let your pi-bonds be pi-bonds.


I have prepared students for the TACHS, SHSAT,COOP,and HSPT and scored in the 99th percentile in the COOP and HSPT myself. Using my background in Latin, I help students break vocabulary words into their bases. Math is usually the most difficult area, so I spend the most time here and stress estimations and proportions. Students usually see how verbal proportions are analogies. I focus on the common ideas in Grammar and Reading Comprehension and use paper cutouts to elucidate the tricky "Abilities" section of the TACHS. I use expected value and other mathematical techniques to teach optimal strategies for test taking.


At first, physics didn't make any sense to me either. Before this, most of school is memorization and regurgitation, but physics is more of a way of thinking. After patiently working at it, something clicked and it transformed the way I look at the world. This valuable method of thinking is applicable across many disciplines. Chemical Engineering is the study of applying many of the same phenomena in kinematic physics to liquids and gases instead of solid blocks.


There are many nuances to the Regents that anyone unfamiliar with the test could waste a lot of time solving problems the long way. On tests like these, time is your worst enemy. I can show you how to optimize your time, familiarize you with their logic, and strengthen any weaknesses in your knowledge so that you can get your highest score possible. I have successfully tutored many students from schools such as Pace, NYU, Columbia, Stuyvesant, SI Tech, Xavier, LaGuardia, Murrow, Brooklyn Tech, Sacred Heart, St. Joseph Hill and many others.

SAT Math

I scored exceptionally high on the SAT Math section in high school and have helped several struggling students improve their score drastically. I have seen every type of question asked backwards and forwards, perfecting a method to identify and most optimally solve each type of problem. This is more of a method of thinking consistent with many science classes. If the student’s algebraic, geometrical, or logical foundation is not up to par, I can help build the student’s mathematical toolbox. I learned the value of an excellent tutor firsthand for SAT Math. She was able to offer keen insights and tricks to solve problems on the test where time is so valuable. I will sometimes use a timer for a problem to get the student used to thinking quickly and clearly for the test. My sessions can be rigorous and intense but very rewarding.

Cooper Union for the Advancement of Science and Art (Master's)

Fantastic Tutor John walks in the door and starts talking Chemistry. His teaching is dynamic and interactive. After struggling through an honors chem class for half of the year, I engaged John to tutor my son. The class was geared towards taking the SAT 2 Chem exam and my son had been scoring well below class average on many of the exams. Long story short, with John's help he ended up scoring 770/800 on the Chem ...
