I read all the Manhattan Prep books for the GMAT, but didn't fully grasp the concepts until the working with Sergey. He boiled down the theory to simple, memorable tricks which significantly boosted my score. Furthermore, the tricks he gave to continue improving my score worked - after attempting the GMAT 2 times, I got the score I wanted (710). Sergey was so helpful in answering my questions, following up with me, and calling me to offer very helpful advice. You really feel like they want you to succeed :)

Sergey provides excellent materials that helped me develop the skills I needed for the GMAT. His workbook does a great job introducing you to GMAT questions, and their online practice platform is excellent for simulating a real test environment. I also benefited greatly from the one on one tutoring that he offers as part of the GMAT Mastery program. Thanks to his support, I was able to achieve a GMAT score of 740! I would definitely recommend him to anyone preparing for the GMAT.

Sergey is one smart guy and also a very nice person. He will go out of his way to help you on studying for the courses. He possesses a strong knowledge of GMAT and MBA which helps students get advice on MBA Admissions. He is very good at teaching both Mathematics and verbal, and provides multiple techniques to resolve questions. I am currently preparing for GMAT and these sessions have taught me very useful techniques that have helped me in my preparation. The sessions are meant to teach you different way to approach questions and resolve them quickly which is a very important in a GMAT exam.

I was able to score a 760 within 2 weeks of finishing my sessions with Sergey. A few months later, I got into the Wharton MBA! I wanted to be as efficient as possible with my studying, and figured that the best way to do that was to learn the skills required from professionals. My diagnostic score was 570, and Sergey helped me improve almost 200 points in 6 weeks. The experience was extremely valuable, would recommend it to anyone looking to take the GMAT. A huge thank you to Sergey for being very supportive throughout, and helping me achieve my goals.

Before I started working with Sergey I had just completed my first GMAT exam and scored 650. My goal at that time was to raise my score in order to be competitive for a scholarship to a Canadian b-school. My second GMAT attempt netted a 740. There are a lot of GMAT prep programs out there that offer useful classroom learning to eager b-school hopefuls. Sergey differentiates himself from competitors by taking the time to understand his students and help them to not just meet but go beyond their initial goals. The biggest value takeaway for me was how Sergey helped me navigate the MBA tour and recommended me to look into top American b-schools. I ended up accepting the admissions offer from UC Berkeley Haas School of Business, and I'm extremely happy with the choice!

Aside from being one of the nicest people you'll meet, Sergey is a natural teacher who brings forward the perfect mixture of patience, smarts, compassion and humour. He genuinely cares about your academic journey and is always there to lend a hand of support. He was, and continues to be extremely responsive in every aspect. I couldn't speak more highly of Sergey and the quality of his curriculum. If you're thinking about working with Sergey, I would highly, highly recommend him.

Sergey is an incredible coach, and he helped me significantly for the test. There is a lot of content to learn for the GMAT, but his sessions broke it up very thoughtfully, to make it manageable, and it's great for staying accountable to deadlines and to your goals. There was a great mix of learning the content, strategic problem solving methods, and actively doing questions on my own to test my understanding, and to help me practice. Sergey was a great coach.

I knew from the beginning I had to focus on verbal and Sergey helped me understand how to attack each argument. Best part is the team is always there to answer any further questions and motivate you throughout the process. Easy to follow answer explanation videos helped me to identify patterns and shortcuts to understand the logic behind each question.

I took the GMAT 4 times prior (studying on my own), with scores raging from 690 to 710 - not a bad score but definitely below the average for a top US MBA. Working with Sergey gave me the foundations I needed to increase my score to 740, pushing my score to above the 730 avg for top b-schools. I have received interview invitations from the two schools I applied so far (CBS and MIT), which is a good measure on how the score has helped me so far. Thank you Sergey, I really appreciate your help and support!

Sergey is a very caring individual who only wants the best for all of his clients. He spent countless hours helping me. I can't thank him and his team enough for the tremendous amount of support I received throughout the whole process. I highly recommend working with Sergey if you are looking to do well on the GMAT.
