What Our Students Say

"Bob is very invested in his students and genuinely cares about each person getting a good score. I was working for months to get a 655+ on the GMAT Focus and couldn't break that ceiling. Bob encouraged me to take the test one more time and I scored way beyond my target."

"I have been being tutored by Bob for 1.5 months and have improved my score to 720 from the 590 I originally scored on the GMAT. He provides 100 PS and DS problems on each topic tested on the GMAT that we work together in each session that have helped me master each concept. I no longer panic when I look at a GMAT math question - Bob has taught me to identify each type of problem and then utilize a specific strategy to complete it. I came to Bob very disheartened by my low score after taking a prep class and studying independently for 3 months. I honestly did not think I could learn the GMAT math, but now I feel confident with each topic! I had not taken a math class in 7 years, but Bob's tutoring has sharpened my analytical skills and taught me new concepts I didn't think I could learn after being out of the classroom for several years. I highly recommend investing the time and money to be tutored by Bob. I wish I had not wasted my time and money on a prep class and had used Bob's individualized tutoring service from the beginning!"

"It has been an absolute pleasure working with Bob throughout the GMAT prep process. Bob is truly one of a kind. Before we started working together, I took a Manhattan Prep course for the new GMAT Focus exam and struggled considerably in the Quant section (which surprised me, given that math was always one of my stronger subjects in school). I could not manage to score higher than the 58th percentile on practice tests. After working with Bob for 3 months, however, my Quant score on the real exam landed in the 94th percentile. Moreover, my overall score improved by exactly 100 points. Bob has years and years of experience and knows this test inside out. With a bank of THOUSANDS of practice questions, he exposes you to EVERY single question type you might encounter on the exam. On top of that, Bob is one of the most caring people I've worked with and is so invested in his students. In the beginning, when I first looked into GMAT prep courses and tutors, I felt overwhelmed by every program claiming to be "the best". It was hard to know exactly who to believe. But I can now assure you: Bob is just that. Working with him was the best investment I could have made, both in myself and in my future."

"Bob is the best! Before I met Bob, I had trouble improving upon my 660 official GMAT score. No matter how much I studied the concepts, I just could not score anything higher than a 660 on my practice tests. After spending two months of tutoring with Bob, I'm happy to say that I scored a 700 on my official GMAT last weekend (4.24.2021). Throughout my learning experience with Bob, he was very professional and knowledgeable about all Quant concepts on the test. He helped me master key concepts that no doubt helped me get that 700 score. Bob was also flexible with his schedule, and was willing to accommodate whatever time worked best for me. I highly recommend Bob for people who are currently in the ~600 GMAT range, and are looking to get a 700+ score on their GMAT."

"I highly recommend Bob to anyone preparing to take the GMAT. Before I first met with him, I scored a 36 on the quantitative section and felt completely overwhelmed by the exam material. After working with Bob for 6 months, I brought my score up to a 47 and was well prepared for any question that could have been asked. For anyone who has taken the exam and knows the anxiety that comes with seeing a question you have no idea how to answer, I promise that you will leave your time with Bob with full confidence in your ability. His format of isolating different question types and taking a deep dive into each section simplified the exam's complexity and allowed me to quickly recognize and solve the questions presented. Not only does he have a deep understanding of the material, but he is skilled is his ability to teach effective methods in an easy-to-understand way. This isn't a standard course where you feel like time is being wasted – Bob immediately jumps into the material and spends every allocated second working to make you better. I didn't just learn how to take the GMAT, I learned how to be a stronger thinker. While Bob won't shy away from calling you out for simple mistakes, it is because he truly cares about his students and recognizes your potential to beat the GMAT. I'm so glad I took the time to work with Bob, as I wouldn't have reached 700 without him. Side Note - when he says to make a notecard, MAKE A NOTECARD. I didn't do that for the first 2 months, which definitely slowed my progress down."

"Bob is an amazing tutor that helped improve my GMAT score dramatically. My Quant skills improved so much with his help. Bob helped me to solve complex math problems using quick methods by showing me a lot of math tricks to save time. For each math concept, he gave over 100 practice problems as homework to help me master the concept. Whenever a concept was difficult for me to grasp, he worked with me to understand the topic, and would give me extra problems to work through. Bob designed the course work based on my strengths and weaknesses. His materials are well organized and divided into medium difficulty to hard. He stresses the importance of focus and building stamina for the 3 hour GMAT test to ensure success. He helped to build that stamina while encouraging and motivating me in each step of my GMAT prep. Bob is also very flexible with his student's schedules. He understands that his students are busy, and will work with them to meet very early in the morning or late at night to accommodate their schedules. I highly recommend Bob's services to all of those who want to achieve success on the GMAT."

"Each hour with Bob is worth every penny. If you follow his instructions you should be able to bump your quantitative score above a 43-45. I could not be happier with my experience working with Bob. He only works with one student at a time to better understand your specific needs. He is patient and understands that people learn these complex math concepts at different speeds. Bob not only teaches you the math but also different test taking strategies that I have seen first hand on the actual GMAT test."

"I highly recommend going to Bob for GMAT tutoring. I've been going to him for several months now and I'm happy to say that my quant skills have improved significantly. He customizes his approach so that I'm mastering the concepts which I need to learn most. Bob gives me over 100 questions for homework and will always give me more problem sets if I ask. His materials are organized well and engaging - I actually look forward to doing the homework and going to sessions because it's fun! Thank you Bob for making me feel confident in my ability to do well on the test!"

"If anyone is looking for GMAT Tutor in New York Bob is the one you have to go for. He helped me to get a GMAT score I needed. GMAT Quant section was a challenge. Thanks to Bob, I did it with the help of Bob. I thought to give up GMAT after looking into my test scores before meeting him. But after meeting Bob and got tutored by him I just wondered why didn't I go to him before. He taught me many techniques to solve the problem in less than a minute and some cases in a few seconds. And coming to his personality he is a very nice person and he is always approachable to his students whenever they needed him. His patience level and calmness were very high. Such an amazing person he was."

"Bob is a great teacher and very personable in his approach. If you want to pass with good/top scores, he's the person to work with!"

"Great tutor. I took classes with Bob for two months and it helped improve my scores drastically. He teaches you how to think through the GMAT exam. Bob gave me lots of homework on each concept. He was able to really improve my quant skills through our in class work. I would definitely recommend Bob to anyone looking for a high quality GMAT tutor in the NYC area."

"There's a reason why Bob is such a great GMAT tutor-it's because he knows the GMAT better than anyone else. Bob spends over 12 hours a day, 7 days a week with students teaching the GMAT. So he knows what kinds of problems you will see and the concepts behind them that are the most important. He's tutored so many students that he can tailor his tutoring to anyone's learning style and is very accommodating. Bob brought my score up significantly and I couldn't recommend him enough!"

"Bob was instrumental in helping me succeed on the GMAT - I could not have reached a 740 on the GMAT without his tutoring and guidance. Bob has created an incredibly comprehensive tutoring process to cover all the relevant Quant topics, but he doesn't take a one-size-fits-all approach to his students. When we first began our sessions, Bob tailored the materials to best fit my needs and pulled together custom sets and questions that helped me build a deep understanding of the materials. He supplied countless flashcards and homework that I could study in my own time, as well. In addition to sharing his incredible math knowledge, Bob showed so much patience with me and offered encouragement every step of the way. He not only taught me the Quant skills I needed to be successful but also never wavered in his support of my progress. Bob helped me develop the confidence necessary for the GMAT. I wish I had found Bob sooner in my GMAT studying process. He blows the major prep courses out of the water. I cannot recommend his services enough - he will do everything to help you score your best."

"Bob was a tremendous resource for me during my GMAT prep. I had studied for the GMAT prior to meeting Bob, but could not improve my score on my own. Luckily I found Bob, called him up, and that quickly changed my GMAT troubles. Before, I used to dread doing math, but with Bob, I started to really enjoy the process of doing complex math. After working with Bob for 3 months, my Quant skills drastically improved! Bob taught me unique methods for solving complex equations that saved massive amounts of time. We hammered away at all the quant concepts during our study sessions together and for each concept he would provide me with 100 practice problems as homework so that I could work towards mastering the concept. Some of these concepts included number properties, exponents, matrix problems, and data sufficiency which I struggled with and Bob broke them down very thoroughly for me. Sometimes, if I needed extra homework, I would text or call Bob asking him for more material and he would always be happy to help me out and send extra files for me to work on. Bob was able to recognize my strengths and weaknesses and cater to improving those which I did not fully command the subject. It got to the point that Bob knew my abilities so well and could tell me when I was missing a problem not because I did not know the concept, but because of little silly mistakes from not focusing. With Bob's unorthodox methods, we were able to build up my stamina for solving complex GMAT questions and reduce simple mistakes that are costly on the GMAT. Bob is also a really cool, personable guy as well. He cares about his students and their success, he cracks jokes during the lessons which make them fun, and he is super flexible when it comes to working with your schedule. Sometimes, I would have to reschedule and Bob was more than accommodating. I am extremely thankful that I found Bob and we were able to work together. Without him, I would not have made the wonderful strides in improving my quantitative skills. I HIGHLY recommend Bob to anyone trying to achieve their GMAT goals. You would be doing yourself a disservice if you did not utilize Bob as a resource for your studies. With his help, he will mold you into a GMAT test taking machine like he did with me!"

"Bob helped me improve my GMAT score in a short time. He quickly understood my weak areas and focused on those problems sets. He showed me a good number of tips, tricks and shortcuts in tacking GMAT. I recommend Bob for those who want to obtain 700 and above GMAT score."

"Bob is a great guy. Very helpful and knowledgeable about the quant section of the GMAT. He helped me improve my math skills and abilities while being extremely kind and understanding when a concept was difficult or need further explaining. Believe me when I say my math skills weren't in very bad shape. I would dare go as far as saying Bob is a miracle worker in all things math and improving my quant score on the GMAT. Don't waste your time looking for anyone else for GMAT prep, he is your guy!"

"Bob has been an incredible tutor! If you are looking to take the GMAT he will give you the best tricks to save hours on the test. I was recommended by a friend and could not be happier with the results so far. He will also give you a lot of practice problems so you are prepared for the next lesson. Math has never been my strength, but I am so much more confident now!!!! Thanks Bob!"

"I have been studying for the GMAT for several months, but I had plateaued on the quantitative section and felt uncomfortable with many of the problems. Bob has been a game-changer for me. He has helped me understand concepts in a way that Manhattan Prep never did. He is patient and has the ability to clearly break down each problem type. He has an enormous amount of problems that he can give for additional homework, and he is always responsive over text if I have any questions. In the few sessions I have done with Bob, he has increased my confidence level exponentially and I feel that I can reach my desired score with another few weeks of tutoring. UPDATE: I took the exam and scored a 740! I truly think that Bob helped me raise my score by at least 50 points. I went twice a week for almost two months, and it was well worth the investment! I can't recommend Bob enough."

"I was pretty scared to take the GMAT after being out of school for 6+ years. I took practice tests and didn't remember anything from school. I knew I wasn't ready to take the test so I decided to get a tutor. Bob came highly recommended and when I met with I knew it would be a good fit. I thought about doing other group tutoring sessions but I knew I wouldn't get much out of them. The one-on-one tutoring was so helpful. Bob teaches you everything you need to know about the quantitative section. He teaches you ways to solve problems the quickest. Without him, I would take several minutes to answer 1 question. I plan on having him tutor me for the verbal. Trust his process! I am beyond excited to take the GMAT in a few weeks. Never thought I would be excited to take a test but Bob has given me the tools and confidence to do well."

"I took the GMAT once and was unhappy with my score. Now I am working with Bob and I feel way more confident in my ability to take this test. I understand all of the components of the test much better than before, and he has taught me amazing tricks. He has so many original problem sets so that you always have practice problems to go through. I highly recommend him as a GMAT tutor!!"

"Bob is an excellent GMAT tutor. All tutoring sessions are one on one and he customizes the lessons plans for each student's needs. He is so patient, kind and motivating. I highly recommend Bob for anyone studying for the GMAT. His tutoring services are 100% worth the investment."

"I give Bob my highest recommendation for anyone dedicated to reaching his/her highest possible score on the GMAT. He is competent, patient, and teaches everything needed to excel in the quantitative section in a methodical manner. My GMAT score is a testament to Bob's instruction. I began the process of studying in Feb 2017 and scored a 480 on my first practice test after being out of college for 6 years. I wasted my money on a Princeton review course and I wasted my time trying to master the tricks and gimmicks in the course. While it's true these methods will help improve one's score, I found that despite my greatest efforts I couldn't crack the 620 mark on any of the practice tests. I started working with Bob in May 2017. I scored a 740 in late Jun 2017 because Bob made me smarter (it's really that simple)- letting go of the Princeton review and working with Bob turned out to be one of the best decisions I made with regards to my future. If you choose to work with Bob, I recommend 2-3 days per week. Be humble and let him teach you everything you need in order to excel in the Quant section. Most importantly, spend time everyday practicing and reviewing the concepts visited in each class. I didn't use him for Verbal, but I imagine he applies the same structure to his verbal sessions."

"Currently, these tutoring sessions for GMAT have been a HUGE improvement to my overall test scores. I'm embarrassed to share my original score but it increased by 110 points. Not only did I improve, but I was able to take home the right materials to ensure my understanding. I expressed to Bob that my Quant scores were low and he focused on that area specifically. I would only recommend Bob if you're serious about improving your score. Thank you Bob."

"Bob was an amazing tutor! The way he taught the quantitative section was incredible and really helpful. I improved 20 points because of him. If you need help with the verbal section, I would try to find another tutor; however, if you need help with quant, Bob is your man! He is so kind, funny, and helpful with regard to providing you with the best tips and tidbits with the GMAT. Use him!"

"Bob Chaparala is an amazing person, full of wisdom and understanding. He encourages his student and has various techniques in solving problems. He takes his time to teach, understands how his students learn and how they also understand things differently. His lesson are customized for each individual. I will recommend Bob for anyone in New York, who wants that affordable Tutor and a high score in GMAT. Thank you Bob"

"I've never had a GMAT tutor like Bob! He is very thorough, explains things easily and his office is beautiful! My scores went up tremendously since I have been seeing Bob, can't thank him enough."

"Bob is the person you need to prepare for the GMAT. He is patient, understanding of the student's needs and has an unmatched knowledge of the material. Bob can help you obtain the score you are working for it you are prepared to put in time. I would and will recommend his services to anyone preparing for the GMAT."

"I used to struggle a lot before I met Bob. He has been so helpful and is a great GMAT tutor! He is so patient with me and my quant score has improved. Could not ask for a better experience, thanks Bob!"

"I highly recommend Bob for private GMAT tutoring. I scored in the 96th percentile with his help. He understands the structure of the problems and helps you understand the logic behind what each concept is testing. He is very patient but will push you to work hard and achieve the results you want. He is also very funny and caring. I call him GMAT Grandpa (and still do) among my friends - he takes the time to personally invest in you. Thanks, Bob!"

"Bob is flexible in tailoring his availability to your schedule. He gives great explanations of the crucial concepts and ensures you understand before moving on. I would highly recommend for anyone looking to achieve a high score on the GMAT."

"He teaches us all the tricks! Highly recommend Bob for anyone looking to take the GMAT. He is very flexible based on your needs and is willing to dedicate time to certain sections based on your comfort level with the subject matter. Such a kind person, it is a joy to come to his home every week!"

"I decided to get my MBA about a month ago, and I was lucky enough to find Bob to help me with the preparation. Prior to meeting Bob, i had very low confidence in my math abilities. I even prefaced our first session by telling him how horrible I was! Bob is the most patient, intelligent, and kind person. Not only is he the best tutor in ANY subject I've ever had, but he also makes you feel so comfortable and at home in his office. He connects with you beyond his tutoring sessions, and gets to know you as a person. This is especially helpful because he learns your personal learning style, and presents the info in a unique way to you. Not every student is the same, and he gets it! If you are serious about getting into an Ivy League school, do yourself a big favor and call Bob!"

"Bob is the best GMAT tutor I've used in New York! His study strategy is customized to meet each individual student's needs. If you want to a 700+ score, I would highly recommend tutoring with Bob!"

"My experience with Bob was less than ideal. Although Bob is very knowledgeable about the GMAT topics, he failed to understand my individual needs. The private tutoring with Bob was a supplement to my already extensive GMAT practice. I had been studying for a few months prior to my initial meeting with Bob. I came to him with specific problem areas and with only 6 weeks until my exam, asked that we focus our time accordingly. He did not adhere to my request. Additionally, he would say things like 'wow I'm surprised you got that one correct' or (4 days before my exam) 'you're taking a practice exam on Monday right? Not the real exam. YOU ARE NOT READY.' For someone who is hired to be an educator, the aforementioned quotes are obviously off putting. During the time I did spend with Bob, he was constantly answering texts & phone calls. His phone was on ringer and would go off 10-15 times during a 2 hour period. His attention was NOT undivided. Good luck to all those studying. UPDATE 9/16 - Although Bob and I did not align well, he did make amends by offering financial compensation for the time spent, as well as other resources that may be useful to me in my studies."

"Bob chaparala is an excellent gmat tutor. He is patient and encouraging. He taught me a great variety of techniques to use in answering questions. My scores went up by 150 points. Bob also gave me a lot of practice problems to work with and was always there to answer any questions I had and helped me tackle any difficulties. He customizes the lesson plans for each student needs. Whenever I needed to reschedule, bob was always happy to accommodate that. Thank you bob for being a great tutor and mentor. I couldn't have done it without you."

"Bob has worked wonders for me and my GMAT score. He will work with you to discover any difficulties you're having on the quantitative section, and has hundreds of questions to give you as practice. Countless students of his have gone on to Ivy-league schools due to his help. Highly recommend!"

"Bob is flexible to work at any time that you need, including weekends. His question sets are very specific and prepare you very well for the real exam. I had been struggling with the quant section for a long time, and he helped me increase my score to a 49 (6 points higher than what I got after I did a class through one of the big names) and a 740 overall. Highly recommend to anyone looking to get above a 700."

"I had a great experience working with Bob. He was very patient, supportive and cared very much about his students success. I would recommend him to anyone who is looking to get started with GMAT practice and furthering their education"

"I started working with Bob in Jan 2018 having now worked with him for almost two months I am much more confident in my abilities to tackle the Quant section of the GMAT. He shows, not just tells, you the best ways to tackle each type of problem. Working on practice problems at this point, I do not come across any mid-tier problem or lower that I can not do correctly in a matter of seconds. This is huge since every second not wasted on an easy problem is that many more seconds you have for the harder ones. Now moving into the higher bin problems I am starting to see the same progress in mastering these concepts as well. As some of the other reviews have stated, ditch the Princeton Review and get Bob to show you the most efficient way to think about and take the test, it is worth every penny. I will take my test at the end of March and will give score comparisons then."

"Bob is a great tutor! He gives me so many practice problems and really walks through the problems thoroughly during the sessions. He is flexible and always finds time to fit me in and answers my questions. I highly recommend Bob."

"Without Bob I could not have dreamed of doing as well as I did on the GMAT, he brought my quant score up tremendously. I highly recommend him to anyone looking for a top score and admission to a top program."

"Bob has been a huge help in preparing for the GMAT. He's knowledgeable and understands which concepts and principals to focus on. Would highly recommend"

"Bob's method will push you and will make you comfortable with the most difficult GMAT problems. He helped me raise my score from a 650 to a 740."

"Bob is an amazing tutor! Extremely patient, friendly, and accommodating. My quant score was raised several points after working with him for about two months. I highly recommend him!"

"Bob is a great tutor. He's super hands on and has years of experience. I definitely recommend him to anyone looking for a affordable yet prestigious tutor in NYC. My experience with him was very beneficial."

"Bob Chaparala, a blessed man of humble significance. He is extremely kind and generous. With patience and wisdom, among his many attributes, he positively impacts the lives of so many individuals. Bob, I thank you for making an indelible mark in the lives of others."

"Bob is very professional, easy to reach, and personable! He is dedicated to helping his students and its easy to see that tutoring is his passion."

"Bob, you are a great teacher. Thank so for all your help. I recommended you to my friends and will continue to recommend you to anyone I know who is taking the GMAT."

"Bob breaks down math problems in a way that is very easy to remember. Make a notecard every time he tells you to do so, I find that very useful. He will work around your schedule, I had sessions with him on weekends, early mornings, and late evenings as well. Overall he is a great tutor, I would definitely recommend him."

"Six weeks ago, I took the Official GMAT Test and I scored a 540. To improve my quantitative scores, I sought the help of Bob. For about a month, he tutored me on how to tackle advanced GMAT topics. Further, he showed me how to successfully complete each problem within a given one and half minutes (the ideal time one should spend on each question in order to complete the section). He quickly went through most of the important GMAT topics along with me and routinely emailed me problems ranging from an elementary levels all the way to the most difficult level for homework. Additionally, Bob was very accessible in meeting at times that accommodated my schedule. His effective tutoring methods helped me improve my GMAT score in a very short time. For each GMAT Math topic. He laid down the basics in an easy-to-understand format. His organized materials really helped me to learn concepts much more quickly than I would have through a conventional GMAT class. He also has a unique technique to tackle the Data Sufficiency Problems, some of the more challenging problems on the GMAT Math section. Though he advised me to wait for another month to shoot for a 700 score. I went ahead and took the GMAT test again just a couple of days ago so I could meet my MBA application deadlines. I scored a 40 in Quantitative and a 38 in Verbal, which generated an official GMAT score of 640. I was amazed and delighted to have improved my score by 100 points in such a short period of time with the help of Bob. If I decide to reapply to other MBA programs, I will definitely work with Bob again in my preparation to get above a 700 on the GMAT."

"My test score has improved!! Bob is a great guy. Easy to work with, and very helpful!"
