"My daughter has worked with Dr Donnelly for the last three months and it has been wonderful. Dr. Donnelly has been able to focus on her weaknesses and provide enormous insight. In addition, his advice with regards to strategy for the test has been invaluable. He is able to engage students and provide support well beyond other tutoring services. He is sincerely committed to student success and offers a personalized service with sound methodology. Within 3 months her scores improved significantly. In addition to all his talents ... he is just one of those really smart people that can teach."

Deborah W., Bergen, NJ.

"The fundamentals I learned from Dr. Donnelly were very helpful. I received the one-on-one attention that I did not receive in the Kaplan prep test. I did not feel embarrassed to ask basic questions. Dr. Donnelly was very patient with explaining concepts in detail until I understood. Additionally, he was always available via email or phone."

Neelu V., Manhattan, New York.

"I scored a 700 on the GMAT earlier today. I improved in Math quite substantially, from a 44 (70th percentile) the first time to a 49 (88th percentile). I'm pretty thrilled. I wanted to say THANK YOU very much!"

Brian M., Boston, MA (online student).

"Dr. Donnelly's private tutoring stands apart from other mainstream/commercial review programs because he isolates an individual's weaknesses and tailors a successful review and test-taking strategy that conforms to an individual's needs -- rather than those of the masses. Dr. Donnelly was able to quickly understand and dissect my thought process in order to help me break old habits and establish stronger test-taking skills so I could get that higher score I wanted."

Jacqui S., Manhattan, NY.

"Dr. Donnelly is a wonderful teacher. He is quick to pinpoint weaknesses and, in many cases, turn them into strengths. He always has a structured lesson plan and pertinent homework assignments and puts aside time in the lesson to go over "trouble problems" from the previous lesson. I highly recommend taking a prep course with him. His patience, humor, and kindheartedness makes an otherwise uncomfortable standardized test almost enjoyable."

Mia P., Manhattan, New York.

"Dr. Donnelly has a real knack for explaining topics in plain English and for making them come alive with real-life examples. I would encourage anyone who needs to get up to speed in their preparation for undergraduate or graduate studies to give Dr. Donnelly a call. You won't regret it!"

Mike H., Greenwich, CT.

"Dr. Donnelly was patient, kind and willing to work with me in various areas to help improve not just my score but my understanding of the questions. His schedule is flexible and he is willing to work with you to give you what you need. My score went up dramatically and I would recommend Dr. Donnelly to anyone."

Jodi B., Manhattan, New York.

"Dr. Donnelly is patient and supportive and is clear when explaining questions that were challenging to me. He also urged me to work out questions on my own, which was extremely helpful. He created an atmosphere in which I looked forward to the challenge of each section on the practice tests, and I definitely felt more confident taking the test. If I need to prepare for another standardized test, I will definitely contact Dr. Donnelly."

Pauline E., Brooklyn, New York.

"Dr. Donnelly taught me clearly in a very short time. It was very effective just before my exam, and the results turned out to be great! He was nice and encouraging, and I enjoyed his lessons."

James R., Manhattan, New York.

"Dr. Donnelly substantially improved my verbal score and confidence level on the GMAT. I received a 600 before I met with him and after our sessions I received a 660. Dr. Donnelly showed me many techniques that books and previous tutors did not. Thanks a lot Dr. Donnelly!. I appreciate your help immensely and will refer anyone who asks to you."

Amir B., Manhattan, New York.

"Dr. Donnelly provided me with the tools that I needed to succeed on difficult problems and take my GMAT score to the next level. I took the GMAT yesterday and got... in the 73 percentile in the Math section. This is right where I needed to be."

Brendan W., Manhattan, New York.

"I got a 700 on the GMAT on Saturday. 95% verbal and 68% math. Thanks again for all of your help."

Anoop V., Manhattan, New York.

"My daughter is a conscientious student. She put in a good amount of time with a famous national prep service and did well on her first attempted GMAT. Nevertheless she wasn't satisfied. Within a short period of time working with Dr. Donnelly she had achieved a near perfect score.

Dr. Donnelly made a true difference and I appreciate his expertise and his dedicate. It is truly difficult to move from a 97% to a 99.97% within a few weeks but with Dr. Donnelly's help it was possible."

Jane V., Fort Washington, PA (online student).

“If you are willing to put in the time to work, Dr. Donnelly will make sure you succeed. He is incredibly easy to understand and patient.”

Robert K., Brooklyn, New York.

“Dr. Donnelly's way of teaching is very calm and effective. By teaching concepts in the simplest ways possible he managed to make it interesting and challenging at the same time.”

Maria M., Manhattan, New York.
