I took my first practice test and scored a 640. Based on my undergraduate gpa, I knew I needed to raise this by at least 100 points to be in the running for my target schools. I was referred to GMAT Ninja from one of my good friends, and I began working with Dana just a few weeks later.

Right from the start, Dana and I met weekly to review scheduled homework and test preparation. I asked every question that came to mind, and she helped me formulate a critical process to succeed in the different types of problems and sections on the GMAT. I was amazed at the level of detail in the program ... even to the point of a breathing process if I felt stressed during the test.

Just a few months later, I exceeded my target score with a 760!! I could not have met my goals without Dana and the GMAT Ninja program to give me the confidence and skills to score my best.

I had a very one-dimensional view of the GMAT before talking to David Goldstein. Dave realized that I used to get into a hurried state while practicing for GMAT and he helped me discover this and other biases by making me more self-aware. Turns out that each of us holds a number of blind spots that need to be flushed before we would improve.
Besides the GMAT, the sessions with Dave made me improve as a person and focus on the fundamentals that would make me do well. Turns out it was just a good night's sleep and all turned out well!

I came across GMAT Ninja after months of using online courses with no significant improvement to my score, and in my first session with Bransen I realized I made the right decision.

Overall, I found in Bransen a valuable mentor who not only mastered teaching me content but who also took the time to prepare me mentally for test day. During our sessions, he was determined to uncover my key weaknesses and often went into great detail to explain what led me to make mistakes, such error reviews were honestly a game-changer and made all the difference in improving my score!

I can't recommend GMAT Ninja enough for your GMAT prep, you will have honest and amazing people supporting you every step of the way!

I came to GMAT Ninja having self-studied for approximately 3 months, to decent success. That said, I was aiming for admission to some of the more competitive schools and knew that I needed to sharpen a few key areas (sentence correction and data sufficiency in particular). After a quick introduction with Charles, I was matched with Harry Duthie. I cannot speak any higher of Harry and the work he put in to get me where I wanted to go!
We scheduled weekly sessions where we went over the errors I made on the assigned homework and practice tests that I took. The time he took to explain exactly why my incorrect answers were wrong were truly invaluable and helped 'connect the dots' on the areas where my knowledge base was lacking. Furthermore, he also spent time teaching me the strategy of the test and what questions were worth my time and which weren't. I found this last point particularly effective!

I'll be starting classes at Harvard Business School next month and I certainly couldn't have got there without Harry and Charles!

Harry is one of the best teachers I've ever had for GMAT prep. He was always able to understand how I was approaching a specific question and found ways so that I could continue improving myself. Moreover, Harry does push you, but it is for a good cause. In fact, he will try to lead you to the best score you can achieve and even through in some meditation techniques to help out. I am certain that my improvement in the GMAT and the +700 score was thanks to his tutoring. I highly recommend others wanting to improve their scores to work with Harry.

I had an excellent experience with Dave from GMAT Ninja. By helping to bring much needed structure and rigour to my GMAT prep, Dave helped me to improve my quant score from a 39 to a 48 within three weeks, and improving my overall score by 30 points.

The biggest benefit for me of the process was achieving significantly improved consistency in my results. While I was doing okay in practice exams, Dave's assistance was integral in getting it right on exam day. Dave's approach was warm and engaging, and I have only positive things to say. Importantly, GMAT Ninja's help enabled me to achieve a score I was happy with using for my MBA applications, and to move forward in the process.

I would strongly recommend GMAT Ninja to a friend.

I had my first GMAT exam in June 2020 and scored 460. My motivation and confidence were just gone. I studied without any structure and jumped from one thing to another. Therefore, I needed to find my perfect tutor. After researching online who to choose, I ended up with GMATNinja! (Spoiler alert: best decision ever)

I worked with Alex Cotton (who is quite new to the GMATNinja fam, but I was convinced he’s great after 5 minutes with him). We had weekly sessions and I always received homework to do on my own. Alex helped me to find my motivation and confidence! He has a really positive and fun way to teach, and he always had a good joke in his pocket. The special thing about GMATNinja is probably the approach to solve your Verbal and Quant questions. They’ll give you a guidance to use and to practice, which will make your life much easier. Although, it felt weird to not review my wrong questions (because all those internet websites said to review every single mistake), it was perfect. Alex always reviewed my homework a day before our next session, he gave me honest feedback of my improvements (or sometimes non-improvements), and we went through some questions together.

After all, I got a 610 *yayyyy* in my final GMAT and I got into my desired Master’s program *double yayyyy*!

I feel like having a tutor is not only about what he/she teaches you, but also about that you have somebody watch out for you, check your responses, and guide you!

Dave and his team are excellent. Prior to starting with GMAT Ninja, I was scoring between a 6 and 21 in the verbal section of the GMAT. I was desperate to do better after having invested five months of study time and having participated in a live GMAT course. I decided to reach out to the GMAT Ninja team. I got myself on a wait list and I am so glad I did!

After a couple of months, I was taken off the wait list and began working with Dave. He did an excellent job at pinpointing my weaknesses and assigning homework to specifically address the areas of improvement. He was incredibly patient and diligent throughout the process, providing me with new approaches on how to think of a question and how to improve speed.

Within roughly 2 months, I sat for the GMAT and my verbal score was at a 40!

I highly recommend Dave and his team as they truly care about the success of their clients and will be always be honest!

Custom-Tailored, Stress Free, No BS -- The BEST GMAT Tutors

GMATNinja was the sole reason I was able to achieve the GMAT score I needed. Prior to GMATNinja, I had spent hours and hours using an online GMAT course with little improvement and lots of frustration. Upon starting GMATNinja with Mike, I was put at ease and knew I made the right decision.

Rather than using a one-size-fits-all approach, Mike created a tailored approach for my learning and took the stress out of studying for me. He created custom homework sets that suited my weaknesses so I didn't have to worry or think about what I needed to practice everyday. During our weekly sessions, we would discuss my errors. Rather than asking me to completely change my strategy to questions, Mike would enhance my approach to questions by breaking down my thought processes. This led to significant organic improvement on my part. On certain questions that I especially struggled with in both quant and verbal, Mike taught me smart frameworks I could implement allowing me to confidently answer.

A few weeks into starting with GMATNinja, my GMAT prep became so efficient because of Mike's approach that I was doing more problems sets in less time while experiencing great improvement in my score. I made strides in the verbal section, which had been my biggest weakness. Even in the quant section, Mike was able to help me identify some changes I could make that resulted in me getting a few more points.

I recommend GMATNinja and Mike to anyone who wants to improve their score (no matter their starting point) in a stress-free manner. My only regret is that I wish I would've found them sooner!

I loved working with Dana.

I wanted to break the 700 point barrier and managed to do so thanks for Dana's methodical way of tackling my weaknesses.

Having tried my luck with two other tutors, I especially enjoyed Dana's commitment to understanding my weaknesses before offering solutions to my GMAT difficulties. At the end of the day, the sessions were very focused and I don't think I would have been able to break that barrier without that focus.

I will also say that I benefit from great mental support from Dana and the rest of the team. I ended up taking the GRE and they were able to guide me through the process and coach me on that front too.

I am now very happy at Chicago Booth!

Thank you again
