"710 GMAT score! Stuart taught me some tricks and short cuts that came in handy on the quantitative section of the GMAT, but more than anything else, he helped me settle into a calm focus that helped me perform at my best in the exam."

"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."

"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."

"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!"

"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."

"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 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."

"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."

"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).
