About Me

Tutoring Math, Chemistry, or Physics, I instill a deep level of understanding 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 was a chemistry teacher at Xaverian High School. I earned my Masters in Chemical Engineering from Cooper Union and am a graduate of Regis High School, earning full scholarships throughout my academic career. Since I have received such a great education, I feel that tutoring is one of the best ways to give back and propagate a strong foundation in math and science. I enjoy showing students how easy, fun, and useful understanding the phenomena of the universe can be from a math/science perspective.

Using this method, I’ve helped 7th and 8th graders earn over $9 million in scholarships to high school. In 2021, my students earned over $2.5 million in scholarships.

No Judgement

I familiarize the student with common problems and break them down into simpler ideas that walk the student to the correct solution at their own pace and without judgment. I customize lessons for the student and try to make them as fun as possible. I concentrate on improving your mental flexibility about how to apply the rules to the system. Once understood, you can apply this method to most math and science problems. I seek to I encourage an appreciation for the material, sometimes with puns and jokes.

Preparing Students for the Long-term

My goal is to improve humanity’s math and science literacy one student at a time so that we can make more rational decisions, better solve our problems, and start colonizing the galaxy as soon as possible. Not only do we need to figure out ways to take care of our own planet better, but we also need to spread out among the stars to maximize humanity’s chance for long-term survival. None of our day-to-day problems or legacies matter if humanity is doomed to extinction.

Interconnectedness of Subjects

I prefer to teach Physics, Chemistry, and Calculus as they are thoroughly interrelated; it is hard to tell exactly where one discipline ends and the other begins. 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 always bring my tablet with a multitude of problems and tests for authentic practice. I promote clarity in logic by illuminating cognitive biases and proving them with math. I usually do not allow calculators and encourage estimations, mental math, and fraction use to speed up calculations. I relate much of the obscure vocabulary to Latin bases as I took 5 years of Latin. I promote long-term thinking and an aversion to waste. 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.

John Zaborskis Teaching Background

I passed the rigorous 8 hour long Fundamentals of Engineering Exam(FE) which tested every math and science topic I offer and some. I was a chemistry teacher at Xaverian High School in Bay Ridge, Brooklyn. 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.

Tutored Students from all over NYC

I have successfully tutored many students from schools such as Pace, NYU, Columbia University, Stuyvesant, St. Ann’s, Xavier High School, LaGuardia, Bronx Science, Brooklyn Technical High School, Staten Island Tech, Xaverian/Genesis, McAuliffe, St. Joseph Hill and many others in physics, calculus, SAT Math, chemistry, algebra, geometry, trigonometry, precalculus, high school entrance prep, and Latin. I can show you the simplicity in what you formerly considered was madness like I have for so many.

So that you can get a sense of my style, you can find a summary of the important ideas about pendulums that I wrote for Wyzant here

  • John came very well reccomended. His process included evaluation, tutoring and re- evaluation which enabled us to really understand my daughter's strenghths, weaknesses and progress as she prepared for high school exams. John made sure my daughter was paired with study groups that were a good fit for what she needed to focus on academically. She was challanged, motivated, and had fun with John and her peers while learning. By exam time she was well prepared and very confident . The fruits her and John's efforts were realized this week with acceptances to all 3 TACHs choices, including a full scholarship to St. Joseph Hill Academy and partial scholarship to Xaverian. Congrats to both and thank you to John. Look forward to working with John again as my next middle schooler looking towards high school.

    John helped prepare my son for high school entrance exams. He was knowledgeable about the material on the tests and strategies for taking the exams. My son was accepted to Regis and Staten Island Tech. He also received scholarships to Xaverian, Xavier, and St.Peter's High School. I would definitely recommend John.

  • We are so lucky to have found Master of Chemistry. We used the MOC tutoring lessons for the TACHS exam and are very satisfied with their staff and services. MOC worked with us every step of the way and modified our son's tutoring whenever he needed more help. Our son is a different learner and needed more one-on-one in math. His math tutor, Ireen, was so patient and persistent with him and gave him excellent skill sets for the test. His tests results were very good (better than I anticipated!) and he was accepted into a fantastic high school.I would absolutely recommend Master of Chemistry tutoring to anyone serious about entrance exam testing. Best of luck to everyone!

    Very happy with my son’s tutoring experience with John. It is because of John’s knowledge, expertise and ability to instruct students for examinations that truly prepared my son for the difficult entrance examinations. My son was accepted into the best Catholic high school as well as receiving scholarships to other schools he applied to.

  • John was my tutor for both the TACHs Test and the SATs. I received half-to-full scholarships to every high school I applied to. After a successful highs school career I reunited with John to prepare for the SATs. The results were outstanding! I received the presidential scholarship to every private school I applied to ranging from $80-$100,000. I was accepted into, and chose to attend, the Macaulay Honors Program at College of Staten Island, CUNY on a full academic scholarship. I was tutored in group settings and can attest that John has a way with connecting to each student individually to ensure that everyone reaches their potential. For my family and I John was worth every penny as he’s saved us tens of thousands of dollars over the years. John Z tutoring is the real deal.

    John offers exceptional preparation for the TACHS exam. My son was in a small group with similar ability students. He felt well prepared and confident on the day of the exam. John explained the results of every practice exam at length to me when I asked. My son did an exceptional job on the TACHs exam. He even received scholarships to two of his three choices, thanks to John’s tutoring service.

  • I was looking for a tutor specifically for the HSPT and came across John's website. It was the best decision I made. Not only did my son get into Regis High School, but he got other scholarships as well. He worked with the kids, kept us updated and answered any questions we had. My son gained confidence in his ability to tackle these tests and for that I am grateful. Looking forward to working with John again for my other children. Thank you so much!- Marie - Jan 2017

    Highly recommend! My son was tutored by John for preparation for the TACHS exam. He was part of a group tutoring session, however, all of the students still got a very personalized tutoring experience. John was very open to the students asking questions, and would help the students with anything that they needed during the session. At one point, I was concerned with my son’s progress, and John took the time to have a long conversation with me to discuss ways in which we can help my son further. He then implement those changes, and the end result was my son doing very well on the exam and getting accepted into his high school choices. John is very friendly, helpful, interactive with the students, and very responsive to questions, not only questions my son had, but myself as well.

  • Michael D'Ambrose was an excellent tutor for preparation for the high school testing. Michael worked with my son for 12 months on a weekly basis to prepare for the SHSAT, HSPT and SSAT. Michael was always prompt and often went over the hour time slot. Since the SHSAT covers math that 7th graders haven't learned yet, Michael was instrumental in getting Evan up to speed. As a PhD candidate in chemical engineering, Michael really understands the subject and had excellent success teaching algebra to him. We ended the process with 3 great high school options: Brooklyn Technical High School, Xavier High School Ignatius Scholars Program, and 2 NYC private, independent day schools. We are very pleased with the results and thank John and his team for all of their support, communication and guidance along the way.

  • This is excellent HSPT tutoring well worth the investment. Starting in the summer, we worked with Julian Rhine on John's team a couple of times a week via FaceTime/Skype. Through that and diligence completing more than 10 full practice tests, my son did well enough to get a full scholarship to Regis High School, as well as a full scholarship offer to St. Peter's Prep in JC, and scholarships to Seton Hall Prep and Oratory Prep. A total of more than $250k in scholarship money. THANK YOU for teaching him the skills needed to ace the test and to walk in with confidence. Julian was tremendous and John was a great resource to us as well. You'll be our first call in a few short years when it's time to start thinking about the SAT....Couldn't recommend more enthusiastically!

    I was looking for a tutor for my son and John came highly recommended. He also has excellent tutors that work for him as well. Tim Hadad and Avril Saavedra were wonderful. They were extremely knowledgeable of the material on the exams and of specific testing strategies to incorporate . For 12 months they prepared my son for SHSAT, TACHS, and Regents. My son received two full scholarships to Monsignor Farrell HS and St. Peter’s HS and passed the Algebra and Living Environment Regents with flying colors. I am looking forward to working with John and his staff with my younger son. Thank you very much!

  • John is excellent and his hard work guiding my daughter thru TACHs and HSPT earned her several scholarships and high scores. John and his team are easy to work with and what he gives to his students will show in their scores. He prepares them and gives them confidence and gives detailed reports on his testing. He is excellent and worth it!

    John's tutoring is exceptional and I would highly recommend him! My son scored very well on his TACHS test after receiving weekly tutoring from John. He was very well prepared for the test. Additionally, he actually enjoyed going to his weekly tutoring sessions because John made it enjoyable for them while teaching. Thank you John! Great job!

  • I cannot say enough good about John. He will challenge your child more than they likely have been been but he does it in a way his students will rise to that challenge. My child made honors on all three of her choices and received full scholarships to both Hill and Sea, thanks to John's preparation strategy.

    John is a great tutor!!! He worked with my son on passing the SHSAT test and definitely prepared him for it. My son really enjoyed his hourly sessions with John each week. I can proudly say my son scored 596 on the test and made his first choice, SI Tech. Thank you John for all your hard work and experience throughout this process. I definitely recommend your tutoring services and look forward to working with you again for my daughter.
