ACT help!

Hi Rob,

Just wanted to let you know that with your help Sam was able to raise her ACT score 5 points which now makes her eligible to apply to some of the more competitive colleges this upcoming year. Your support and the strategy around the college exam process was invaluable. Not only did you help access her weaknesses and areas needed to focus on during studying you were able to first suss out which test (ACT or SAT) was most appropriate for her. Even though your profile labels you as a “math tutor” your help with the English and Science portions of the test were so helpful. In fact, she was able to get a perfect score of 36 on the English portion of the exam.

Thank you!

Hey Rob,Just wanted to let you know I ROCKED the math section of the GRE (at least by my standards): 670! That's 60 points better than I did on the SAT and about 170 higher than I thought I'd get. Soooo big thanks to you for all your great help. My dad says thanks, too. Seriously, he told me to thank you 🙂

Hi Rob,

I just wanted to let you know that after three sessions with you Jules got a 95 on his trigonometry final! He was thrilled and needless to say your help made the difference.

I think you were able to clarify concepts in a way that he could grasp and helped him identify the importance of slowing down and being more careful and thoughtful.

Thank you so much. Talk to you soon.

All the best,
Joyce McKee [parent of a student at Stuyvesant]



Just wanted to let you know that Jules got a 98 on his Regents exam and a 96 for his final grade!!

Pretty darn great. Thank you so much. Hope you have a wonderful summer.



Rob tutored my 5th grade son for most of this school year. We were looking for math enrichment he was not getting through school. Rob taught him advanced middle school math once a week.

My son loved studying with Rob and we enjoyed his relaxed and pleasant teaching style. He is an excellent and experienced teacher and I would recommend him as a tutor for anyone who needs help or wants to progress faster.

Guess what?!?

I got a 4.18 on the math test!! 😀 Thank you so much for helping me get ready for the test, I don't think I would have done so well without you. My parents are planning on hiring you again for fifth grade, and if so I look forward to seeing you again.

Rob Cohen was a great tutor to my 12-year-old daughter. She made excellent progress in math during her time with Rob. In fact, math has become her favorite subject! She also learned some valuable math test-taking skills from Rob and subsequently performed very well on several standardized tests. Rob was always punctual, considerate, and patient. I can recommend him highly!

Our daughter was struggling with math, and we desperately needed some help. Rob was instrumental in helping her understand and fill in the blanks that her teachers couldn't. Now we are back on track and she no longer requires additional classes in school. Not only is she scoring higher on tests, but she actually likes completing her math homeworks! Thank you Rob! If we ever need more help, we won't hesitate to reach out to you!

Rob is an articulate math teacher. He is kind and does not rush me about getting things right the first time. When I get a wrong answer, he helps me find what I did wrong and how to fix it. He shows me how I can be sure I don't make the same mistake again.

-Naomi, 8th grader at Baruch Middle School in Manhattan


Rob was a great help with both my 8th-grader and my 11th grader's math homework. Always reliable and punctual, he worked with them in our home, reviewing their classwork and practicing problems, which proved to be very useful for their in-class tests.
