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. – Liz , Breezy Point, NY on 10/15/14
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 in TriBeCa, NY on 7/15/14
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
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.
-Dmitry in Brooklyn at Hunter College for Biophysical Chemistry in Spring 2013
After my son started with John his grades went up and with grades confidence level went up. Additionally, after retaking the SAT after working with John on the Math section, my son went up 80 points. Great tutor. Thanks John!– Gary in Brooklyn 2013 for his son in Physics, AlgebraII/Trig, and Sat Math
