I had a great experience with Tara - my GMAT score increased by 40 points and I ended up getting into every school I applied to, including Harvard! I couldn't have done it without his support. I previously worked with another tutor for 3x as many hours as I spent with Tara and did not see anywhere near the results…

Tara is phenomenal. Originally took a Kaplan(Manhattan Prep) course, scored an official 475 on the GMAT FE. Retook the Kaplan course (for free), but my practice tests were not improved. After studying with Tara, I scored a 645 and will be attending Booth.

Tara was great. I was really struggling to get my GMAT Focus quant score up and wound up doing about 10 hours of lessons with him and got my cumulative score up 30 points. His tips, tricks, and time saving methods are fantastic. Would highly recommend!

Tara has been an exceptional tutor and made a tremendous difference in my GMAT journey. Before working with him, I studied with another tutor and genuinely felt prepared, yet I scored a 525 on my first attempt, including a 30th-percentile quant score. It was discouraging enough that I stepped away from studying for six months. When I finally decided to try again, I began working with Tara, and the change was immediate. He took the time to understand exactly where I was struggling and rebuilt my quant foundation from the ground up. His explanations were clear and practical, and he adapted his approach to the way I learn. On top of that, he was incredibly flexible with my demanding work schedule, often meeting with me early in the morning to ensure I stayed consistent. After a few months of working together, I scored a 615 on my next attempt. It was a meaningful improvement, but I still had a long-term goal of reaching a 645. Tara continued supporting me with the same patience and dedication, helping me build an effective error log and identify the recurring mistakes that had been holding me back. That final stretch of work made a remarkable difference. One month later, I finally reached the score I had been aiming for since the very beginning: a 645, with an 84 in quant, placing me in the 87th percentile. To go from the 30th percentile in quant to the 87th, and to ultimately achieve a goal I had been chasing for over a year, is something I once thought was out of reach. Tara’s guidance, structure, and belief in my potential made it possible. If you are looking for a tutor who will genuinely invest in your progress and guide you through every stage of the process, I recommend Tara without hesitation. He supported me through the full journey, and I could not be more grateful for the outcome.

Thank you so much, Michael, for the thoughtful review. Your progress is a great example of what consistent, focused work can achieve, especially after a discouraging start. You stayed patient, trusted the process, and kept showing up — and that’s what made the difference. Going from the 30th to the 87th percentile in Quant and reaching your long-term goal is a significant achievement, and you earned it. It was a pleasure working with you throughout the journey, and I’m glad I could be part of it. Wishing you all the best with what comes next.

I got a 735 on the GMAT Focus Edition (Q: 86, V: 90, DI: 83), and Tara was an incredible tutor during preparation for the exam. I had gotten a 635 (Q: 75) on practice exams before working with him, and on the recommendation of a friend, I reached out to Tara in hopes of improving my quant score. I did the Level 2 comprehensive course package (and ended up purchasing 2 additional hours for the very advanced content) and we were able to cover a ton of material. In the exam itself, I only got 1 question wrong, and I credit my success to how well prepared I was through working with Tara. I have a nontraditional background for applying to business school – I have an art history degree and work for a nonprofit organization. I had not taken a math class in over 8 years, and my math skills were very rusty to say the least. I was suspicious as to how much improvement I could make in two months, but I gave it a try, and I am so glad I found and worked with Tara. I was really impressed by how well he knew the material that would be covered on the exam. Everything I saw in the exam overlapped with content I had covered with Tara, and he had an extensive collection of notes and practice problems which he shared with me. The morning of the exam, I practiced with three of his “warmup” questions from materials he had shared with me, and it helped me get in the right headspace before the exam. One thing he really emphasized and which helped me immensely in the exam was to make sure you know what the question is asking – and don’t waste time doing work that doesn’t help you get that. I was able to save so much time by using the tricks he shared and by focusing on what the question was asking and not just on solving an equation. I really struggled with time management before working with Tara (frequently running out of time for the last 4-5 questions), and in GMAT I finished with extra time to go back and review questions. It was a big investment of time and money, but it really paid off.

735??? Am I reading that right? Congratulations, Laura — that is an outstanding result. The jump to Q86, especially from a Q75 baseline and after time away from math, is incredibly impressive and a testament to your focus and consistency. Your journey will be very encouraging for students starting with a more modest baseline but aiming high. You trusted the process, put in the work, and executed beautifully on test day. It was a pleasure working with you. Wishing you all the very best with what comes next — and thank you for trusting me with your preparation.

Tara was instrumental in helping me score a 725 (Q: 85 / V: 87 / DI: 86) on the GMAT Focus, reflecting a 70-point improvement, primarily on the Quant section, over the course of roughly a month. Before working with Tara, I was stuck at a 655 after sitting for the exam twice, with my score being dragged down by Quant – Tara’s primary area of expertise. I had been using Target Test Prep, but while the material was extensive, I had plateaued; I felt like I was studying endlessly without seeing results. Using ChatGPT to supplement my prep was marginally helpful, but the explanations lacked context, and there were no practical tips and tricks for addressing difficult questions when my first thought was “where do I even start?” That’s where Tara came in. Per the recommendation of a colleague, I reached out, had an initial call and signed up for a multi-hour package shortly thereafter upon seeing his expertise and approach, which is a differentiated and complementary mixture of both test content and practical strategy. We worked though his Advanced Course, which is specifically tailored to test takers targeting section scores of 85+. The questions he gave me were at the exact right level of difficulty, and he coupled them with insightful test-taking tactics which I hadn’t seen in any other test prep materials. Furthermore, Tara was extremely effective at breaking down and sharing his thought process on the most difficult Quant and Data Insights problems, particularly data sufficiency and multi-source reasoning-style questions that I often would get tripped up on. Lastly, Tara has structured the course in a comprehensive and organized manner, with individual lessons covering specific topics and being paired with highly relevant homework assignments. Beyond the technical prep and strategy, Tara was a great coach and more broadly is an outstanding person. He was entertaining, flexible, and understanding, which made the experience much more enjoyable while balancing a demanding work schedule. On days when I was tired and frustrated, he helped me stay sane; on days when I was confident, he pushed me to capitalize on that momentum. The night before my exam, I used all that I had learned from working with Tara to develop a mental plan for test day – how to pace myself, how to order the different sections of the exam, and a list of concepts to think through quickly in the event that I was stumped on a particular question. The plan allowed me to go into the exam calm, confident, and equipped with the exact strategies I needed, and the results showed. If you’re serious about pushing into the 705+ range, especially if you’ve plateaued with self-study tools, Tara is the difference-maker. He knows the exam inside and out, adapts to your level, and gives you both the technical skills and strategy to perform on test day.

One word. Wow! Congratulations, Alex — this is outstanding.Your improvement, especially in Quant, reflects a lot of focused work and discipline, and achieving this level in such a short time is truly impressive. You trusted the process, broke through a tough plateau, and executed extremely well on test day. It was a pleasure working with you and being part of your journey. Wishing you all the very best with what comes next — you’ve earned it.

Working with Tara was honestly one of the best decisions I made during my test prep journey. I’m based in Mexico and was looking for someone who could really help me make sense of the quant sections for the GRE, EA, and GMAT. From our very first session, I could tell he knew these exams inside out—but more importantly, Tara knows how to teach them in a way that actually made sense to me. I came in with rough scores, especially in quant, and I felt pretty overwhelmed at the start. But Tara was super patient and methodical. We focused on understanding the “why” behind each concept, not just memorizing formulas. That shift made a huge difference in how I approached the test. My confidence grew over time, and the results followed—my DI score alone jumped up by 40 percentile points. One of the things I appreciated most was how Tara always gave me multiple ways to approach a problem. He’d share clever tricks, tools, and different strategies for solving each type of question—so I could choose the one that made the most sense to me. That flexibility made a big difference and helped me become a much more intuitive problem-solver. If you’re struggling with quant or just want to take your score to the next level, I couldn’t recommend Tara more. It felt like I had someone genuinely invested in my success, and that made all the difference.
