"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."

"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."

5 star review

"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."

"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."

"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 gre. 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."
