“Owing to Mr. Sujoy Kumar Datta’s meticulous teaching technique and focus on the basics, I was able to score a 730 in the GMAT Examination with sectional break-up of Q50 and V39. He has definitely filled in my gaps of concepts and has changed my strategy of attempting questions. I am indebted to him”

“The best person to contact for GMAT success Sir was responsible for guiding me through study materials and mock tests to increase my score from initial mock results of 600 to a GMAT score of 720 (Q-50 V-38). Masters at conveying complex concepts in manageable chunks of information.”

“One of the most talented individuals I’ve come across, Sujoy is a great teacher and has the solution to almost any Quant question that I put forward. I particularly liked his teaching style – He didn’t give answers out easily and made you think till you were able to get the solution on your own. He constantly motivated and encouraged me during my GMAT prep. I’d recommend Sujoy to any taking the GMAT. It was a pleasure learning from you!”

– by Fahad Taslim
attended CAT course | CAT 99.84 | IIM Calcutta

“He’s probably the best teacher in Kolkata. If you really want to rise above the mediocrity, he is the one to consult. The concepts are not done in an ordinary way because that is not the point of competitive exams. He carries rich experience and even richer aptitude.”

“Thank you CUBIX for making my son ready for SAT exam. I would like to highly recommend Sujoy and his team for our fantastic coaching experience. We live in USA CA and looking for good coach who can teach mathematics to our son Aradhya. We were fortunate to connect with Sujay and really happy with the progress. He and his team is dedicated in making learning part of students with focussed practical approach. Very discipline and punctual which enhanced learning experience. highly recommended and keep it up CUBIX!”

son attended SAT course 

“If you are a parent like me in the US and are wondering if Indian standards of English teaching will meet your child’s needs, you are not alone. I was skeptical too. But my experience with this institute proved me otherwise. My son is in 9th grade at a public school system in the US. He took the English PSAT/SAT prep Course over summer and it gave him a good head start. Sudeshna maam’s teaching style was very likable to my child. She provided timely feedback. I appreciate the flexibility she showed in rescheduling some classes as needed for us. The material and resources provided were of good value too. To me, this is much more greater value than say signing up for a group class in one of the online well known curriculum’s like Princeton or Kaplan prep because of the one on one focus. My daughter is now doing the same course.”

“Sujoy Sir has trained me for MBA entrance examination. He is one of the best teachers I have come across. The pedagogy which he follows is superb, making sure the student understands the underlying logic of the subject instead of just mugging up the things. I received his full support at every stage of my preparation. It was a wonderful experience. The pedagogy followed is superb. My hearty thanks to the entire team for helping me in achieving my goal that is converted ISB. A big yes to Cubix and Sujoy sir!”

– by Lakshita Sharma
attended SAT mathematics course | Math 760

“I took classes for SAT math for over 6 months and every class in that period was super helpful. I was able to improve my score and learn new techniques that worked best with my personal learning style. Even though I was taking classes internationally, the time was suited to what works best for me, and I was able to ask questions at any point and receive a quick reply. I would highly recommend for SAT prep.”

attended CAT complete course | IIM Ranchi

“Easily, amongst one of the very best in his trade. He has mastered the art of mathematics beyond excellence, and will always be willing to share his wealth of experience with you. No matter which level you belong to, trust him to have a strategy for you to excel. He will go out of his ways to help you out. I often used to seek help on concepts at odd hours of the day, and he almost always came up with a response within minutes. The result was that my percentiles got a boost.”

“Mr. Kumar is one of the most experienced teachers i have met. He knows the tricks to master the SAT. Studying under Mr. Kumar helped me successfully excel my SAT. More than the SAT. He creates a student friendly environment providing a helping hand to students when and where they need.”

– by Amrit Vashishtha
attended GRE Course | Simons Business School | Q170

“CUBIX was a last-minute GRE hack for me. I was juggling between various commitments at the time when I decided to enroll in CUBIX GRE course. The course structure is tailored according to student needs, unlike some other programs. The extensive problem bank allowed me enough practice, the quant section in the real exam was like a cakewalk for me. The faculty is top-notch, encouraging and approachable at all times (they used to address my doubts at 2 AM in the weeks prior to exam). Sujoy’s Sir passion for teaching is unparalleled and his dedication to what he does is inspiring. If you are hesitant about them, don’t be. That is exactly the place you want to be!”

– by Mari Mkhitaryan
attended GMAT QA one-on-one 

“I have completed one-month course of GMAT with instructor Sujoy. This course enabled me to increase my score from Q43 to Q47 (even reaching to Q49 in my practice tests). The instructor also shared some tips and tricks to solve hard problems in an easier and less time consuming way. His customized study plan enabled me to concentrate on my weaknesses and improve my result. He also provided useful material to strengthen the acquired knowledge.”

– by Lola
attended SAT one-on-one

“Sujoy worked with me for weeks to prepare for my SAT math section. I was able to learn more concepts and apply that learning. He is a good teacher to teach you new (and multiple) ways to solve problems. Also, he provides a lot of extra study materials and practice problems. 5 star if you want someone who responds quickly and teaches new tips.”

– by Drew Meyer
attended GMAT QA one-on-one

“When I started working with Sujoy, I was at 42. The day of our first meeting that I knew my search for the perfect quant tutor was over; I mean, the guy is a wiz. From the beginning of our sessions to my actual exam, Sujoy helped me improve from a Q42 to a Q49. Working with Sujoy was a huge confidence booster; he not only helped me with the tricks, tips, and tactics necessary to ace the Quant but also instilled in me the belief that I could actually improve. Having the right mindset is key when going into a high-stakes exam like the GMAT, and I was not worried or nervous at all while taking the Quant section because of the attitudes he instilled in me. Don’t waste your time looking for the right tutor. Just give him a call.”

attended GRE Coaching | Univ. of Delft Netherlands

“I had prepared myself and despite knowing the syllabus, I was unable to increase my speed and was stuck in some crucial portions such as probability and statistics. I had only 1 month left to prepare and we had classes every alternate days. He is extremely friendly and help in every possible way. I had the privilege to get trained under his supervision and finally achieved 162/170 in Quantitative. Had I been under his supervision for more than 3 months I am sure to have achieved near perfect scores. He had the perfect tricks and techniques that helped me boost up my speed and maintain accuracy. He will provide in detailed solution to each and every question with separate doubt clearing sessions. Undoubtedly the best. Very friendly and adjustable. Due to limited time , we used to have classes at 6 in the morning and sir used to me on time. Never missed a single class. The best was his pep up talk before exam, Thank you so much for being such a great friend and guide.”

“Sujoy Sir was instrumental with the fundamentals of quant in GMAT leading to me getting a full score. When I started with Sujoy sir, I was at 46. Sujoy sir has taught me like a big brother scheduling his time according to mine and making me practice the tough sums as he knew being an engineer I would easily do the medium ones. I would whole heartedly recommend him to any GMAT taker for the quant section!!!”

“I had a wonderful experience under the mentorship of Sujoy for Quants and Sanjay sir for Verbal during my GMAT prep. I would recommend anyone interested in GMAT to at least have couple of classes at CUBIX. I wish the team all the success!!”

“My English speaking son took SAT-Math with Mr. Sujoy and SAT-English class with Mrs. Sudeshna. Both of them are hardworking, punctual and sincere teachers. My son liked the way they teach and learned a lot from them. Thank you so much for your skilled teachings from the bottom of my heart!”

– by Sohni Chakrabarti
attended GRE Coaching | Univ. of St. Andrews

“Being an English Literature student, the very thought of doing math for GRE was extremely scary. Before I began my classes with Sujoy Sir, I had nervously told him that I don’t even remember any basic math that I did in school. He confidently told me that he can get me prepared within 10 classes for the GRE quantitative section, and honestly, I thought it was a joke. I could not imagine how someone like me who struggles with simple calculations, can learn GRE math within just 10 classes. But he made it more than possible. He is an extremely patient teacher and the best thing about him is that he identifies your weaknesses very well. He taught me everything in context, explaining the smallest of details just so that I could understand the logic behind even the simplest of equations. He is well aware of the requirements of GRE preps and teaches you all the tricks and techniques needed to ace the exam. With his guidance, I slowly gained the confidence to do attempt difficult problems. I would strongly recommend him for any student who is looking for quality teaching. I don’t think I would have been able to prepare myself for GRE without his guidance and support.”

“I found the technique of teaching very good, specially the ways that were taught to do sums quickly was really helpful. I was helped a lot in English with my vocab and RC, tests were often taken which helped a lot. Further, I even found the teaching environment pretty comfortable so that I could voice my doubts repeatedly even on the same topic and I was always helped. The timings were also very flexible. Overall, the classes really helped me a lot to perform well in GRE.”

“I have been a part of the cubix gmat classroom for the past 6-7 months , went through the rigorous drill of the gmat prep and feel quite confident to share my experience . Seeing an upwards curve in my mocks will write the paper later this month end . Firstly , from my personal experience cubix is the best institute in terms of individually focusing on every single student compared to other institutes . Will be forever thankful to the faculties led by Sujoy sir especially – for the immense customization to study plans , study materials etc they did for me – purely based on my strengths and weaknesses . The question banks coupled with the numerous individual doubt clearing sessions – are the pillars of my confidence on my prep. Thanks team cubix for all the support.”

“My preparation for CAT began in the month of September which was pretty late, at least I felt so. However, with the right guidance from Sujoy Sir, I was able to handle my weak areas well.
