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.

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.

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.

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

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 cannot recommend John and team enough for HSPT prep. My son received full scholarships to his three top High School picks and I appreciated the professionalism and class flexibility that the program provided. We will also be using them for SAT prep when the time comes!

John is a great tutor. My sister got a full scholarship and was accepted into her top 3 schools with his help.

John came highly recommended to me and did a great job preparing my son for the TACHS and scholarship tests he has taken. My son received full scholarships to both Xaverian and St Peters. He also received scholarship money towards Xavier and Staten Island Academy. I already have and will continue to recommend John to others.

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!

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!

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.

John is lit

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

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.

John and his team were very helpful and professional and offered wonderful tutoring services to my son for his Tachs, HSPT and SHSAT exams. My son did very well on his exams and received a partial scholarship due to his high scores on the Tachs exam and I am grateful! I am very happy that I used Master of Chemistry's tutoring services and I would highly recommend.

Used John for Tachs tutor. Great tutor and great person.He has several great recommendations for tutors if he isn't available.

John and his team are excellent! My daughter Emma has excelled in her academia with the support she has received. The TACHS test preparation tests and tuitoring that is provided gave my daughter full confidence that she could achieve a great score and she certainly did! We are thankful, happy and blessed to have been recommended to use John and his services. Everyone on his team will work diligently to ensure that your child(ren) feel comfortable and ready with such a challenging test to take.

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

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.

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.

The Master of Chemistry team was an excellent choice in preparing our daughter for the TACHS exam.

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!

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!

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.

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!!

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 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.

John goes above and beyond for his students, the whole process from start to end was very seamless. He and staff are beyond knowledgeable and I couldn’t be happier with the results. I will definitely recommend his services, and will definitely use him again.

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.
