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!
John does excellent tutoring, because through him my son was able to get into his first choice school, and also full scholarships to all three of his schools choices. I can't wait to use him again for future tests preparation for all my children. Thank you so much John
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.
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.
The Master of Chemistry team was an excellent choice in preparing our daughter for the TACHS exam.
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 was instrumental in getting my son a full scholarship offer to Farrell HS, and an offer to Staten Island Tech. His methods are helpful to my son and are the reason for my son’s success. He also tutors my daughter for SAT. I highly recommend his services.
Great tutor, got me a full scholarship to Sea and Farrell, and got me entrance into SI Tech
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 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.
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.

Five stars is an understatement - it should be 10 stars on every aspect of this business - quality, service. value, professionalism, good communication all are above and beyond. The attention given to my son is astonishing. Taking a chance by reading reviews is well worth it. Your child's education is priceless, and if you want your child to excel to their best possible potential this is the place. Mr. Zaborskis, Kate, everyone involved has one intention - and its the best interest of your child's education. Just remarkable on every level. The patience John has makes all the difference, and it's all the time. John's interaction with each child, and as a group keeps the kids interested, and involved, and the results show. If you want to see a difference in your child's school work, and test grades, this is the place. Contact Master of Chemistry and schedule time - it will be the best choice you can make towards your child's education.
We were so luck to have John as a my son’s HSPT tutor. He is so knowledgeable and passionate about tutoring and very kind. He answers us right away. My son got accepted to the school where he wanted. Thank you John!
John is an excellent tutor. My son got into all of his High School choices and received scholarship offers. John’s classes made the material accessible and he kept up my son’s motivation. Thank you John for the great work

John is lit
I would highly recommend John and his team as a TACHS tutor . My son did exceptional well and both the TACHS exam and the scholarship tests for the Catholic High admissions. I had recommended to some of my friends and family.
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.

John is an extraordinary tutor. He tutored both of my sons. We had tried other tutors but John stood out from the pack! My sons even liked him! Thry both did really well and I am very grateful to John! Could not recommend a better tutor! He tutored one for a high school entrance exam and one for college ACTs...
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!

My son worked with John last year for the 2018, HSPT, Tach, and scholarship exams. He was a semi finalist for Regis, and was offered scholarships to both Xavier and xaverian. John is an amazing tutor and prepares the kids for everything!! Thank you!!
John was very thorough in breaking down each topic area and giving specific test taking tips. He was flexible in meeting times and group sizes. John offered many opportunities to take full practice exams and gave feedback and stats for each.

Excellent tutor. Both John and Elina did a fantastic job providing lot of practice questions in math, English, analytical ability. There were times when we requested new questions to be integrated for the practice exams, and both the tutors happily did that. The tutors were extremely knowledgeable and informative. Kate was so nice and wonderful, talked with us many times, helped us in placing my daughter in the group classes with similar students. My daughter got high percentile scores in HSPT, TACHS, as well as BUTLER Scholar Exam. She was accepted in all the schools and also all honors program. She is very happy that she got in to one of her favorite schools with scholarship. Definitely recommend them for test prep for high school.
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.
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!

“Excellent tutor”
John is an excellent tutor! He has thoroughly prepared my son for his high school entrance exams.
John is an extremely intelligent individual but more importantly he is an effective teacher! I highly recommend John Z.!
If my son needs a tutor in high school I will be calling on John and he will definitely be the one I have tutor my son for PSAT/SAT.
Thank you, John. Thanks so much! -Liz , Breezy Point, NY on 10/15/14
“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 SAT 2. John was pleasant, optimistic, upbeat, and a pleasure to deal with and the proof is in the results. – Michael, New York, NY on 7/15/14
“Highly Recommended Professional Tutor “
We hired John to prepare our son for the NYS Chemistry Regents because he had a history of scoring below expectations on standardized tests. John clarified Chemistry beyond simple understanding of typical daily objectives, and general syllabus. He taught numerous concepts, critical thinking, and the, “how-tos” of analytical thinking; far exceeding the classroom teacher’s criterion. Furthermore, John enriched my son’s sophomore year beyond books, study guides, and worksheets. Specifically, he designed individualized instructional plans that surpassed state standards, engaging my son in the learning process with great success, and tremendous confidence.
John meticulously addressed the relative topics highlighted in Chemistry standards, and regent’s exams. He typically prepared detailed, and carefully outlined study guides. John encourages building from his student’s mastery of key concepts, (i.e. point of reference) instilling confidence with simple, yet thorough, explanations and examples of new, more complex material. As well, John’s lessons are comprehensive, encompassing a wide range of subjects. He ensures his student’s understand mathematical concepts in correlation with scientific themes, while simultaneously building a foundation for future lessons. John clearly knows his subject matter, explaining even the most elusive material in a logical, concise manner.
John engages parents with detailed feedback, evaluating the student’s mastery of concepts and/or prescription for review. In follow-up lessons, he spends extra time reassessing difficult topics with patience, and positive reinforcement. John is truly a phenomenal mentor and “academic coach.” SO, How did my son do on the regents? He passed the Chemistry Regents with flying colors, scoring in close proximity to the top students in the school. We are thrilled to have John as a valuable resource for my son, and look forward to continuing this wonderful relationship in the upcoming school term.

“Excellent Physics Tutor”
My son had some challenges with his Physics. John has been a tremendous help in tutoring my son with his Physics class. He scored very well in his final exam. With John’s help, Physics became one of my son’s favorite classes. Thank you very much, John!!
– Caroline in Brooklyn for her son at Stuyvesant High School in Spring 2013
“Very Thorough!”
John is very punctual and has tremendous amount of patience. He zero’s in on your weaknesses and strengthens them, leading to a very strong understanding of the material. Highly recommend for science and math majors!
– James in Brooklyn at St Francis College in 2013
It has been a pleasure to be tutored by John. I am a pre-pharmacy student at Long Island Univeristy. He has helped me do well in both chemistry and calculus. He is very reliable and very patient. He is always willing to help at whatever time of the day! I couldn’t ask for a better tutor !
– Argiroula in Brooklyn at Long Island University in Spring 2013
After my son started with John his grades went up and with grades confidence level went up. Great tutor. Thanks John!
Additionally, retaking the SAT after working with John on the Math section, my son went up 80 points.
– Gary in Brooklyn 2013 for his son in Physics, AlgebraII/Trig, and Sat Math
“Patient, thorough and supportive tutor”
John is a well prepared patient tutor who easily connected with our daughter. He is well prepared and thorough with his lessons. His strategies are well thought out making it easy for her to get the concept. He is a far superior teacher to her professor at her college. She is actually staring to enjoy chemistry because of his intervention. His very positive and supportive attitude is very encouraging to her. John’s tutoring just keeps getting better. She is almost over in the course and he has helped her tremendously with both her grade and her confidence. John is an outstanding educator.
He is now working with our younger daughter in geometry. Very accessible to both our daughters. Just great!
– Dr Victoria in Brooklyn for her daughters in Rutgers and Murrow 2013
John knows his subject in chemistry well. For me Chemistry is not easy and I was boarding on the line of failing and having to take the course over again. John is teaching me chemistry in a fashion that I can understand and apply. He is an excellent tutor and he addresses the issue exactly in a friendly personality so I am always comfortable asking questions. John doesn’t feel bad if I don’t get the material quickly, he always succeeds in finding a way for me to understand. His patience and listening skills help me the most when I have a hard time with problem and he address that issue exactly. John doesn’t just tell you, he shows you and teaches you in a way that you have the tools to do it yourself. John has gone beyond his tutoring duties by following up to see how I am doing and I am gaining confidence that I can do this on my own. My test is today and for the first time I have confidence I will do well. I Highly recommend him to anyone suffering in chemistry.
– Beatrice in Brooklyn, Chemistry at College of Staten Island, Spring 2013
He is very competent, knowledgeable, and clear in his explanations. He also expands beyond the curriculum and teaches useful techniques/information not mentioned the course provided by the school.
-Dr. Isolda on Staten Island, Chemistry at Staten Island Technical High School, 2013
Before I begin here is a excerpt of what it means to really go over the materials:
“We went over problems that mostly dealt with the Carnot cycle and the second law (q = Tds). Energy entering the system is positive; energy leaving the system is negative (for both q and w). We went over an efficiency problem where work, q at the hot isotherm, and q at the cold isotherm are found. We went over calculating the change in enthalpy, internal energy, entropy, and Gibbs free energy. We calculated the change in entropy through a phase change and noted the similarities and differences between a liquid warming a solid through a phase change (q)”
John knows his material and will provide an excellent guidelines to solving the problems. What is important to me and I’m sure other students are tutors who not only show the solutions to problems, but that also teach you in your level and speed and give you a chance to understand visually what is happening in the problem. And John succeeded in delivering all that. Every problem that we do, he helps me figure out the solution on my own so I can do other problems and succeed on tests. I only wish John would be our professor in my class because I would definitely succeed.
