I signed up with GMAT Ninja after completing a two month self-study course, three OG practice exams, and my first official GMAT attempt. I scored a 660 (V45, Q36) on my first official attempt before tutoring began. As a side note, the highest of my first three practice exam scores was a 630.

Once signed up with GMAT Ninja, I was tutored by Bransen for the next two months. Bransen was great to work with. He helped me to understand and fix my bad habits. Most of my tutoring with Bransen was focused on Quant. After two months, I took the test again and scored another 660, but this time it was a V38 and Q43. My Quant definitely improved, which was my main goal going into my tutoring sessions. I knew my lower Verbal score was a result of my lack of discipline during the test, so I scheduled my third attempt for a month later hoping to score a little higher overall. I knew if I followed Bransen's advice with Quant that I could at least match my last Quant score. I also knew if I eliminated dumb mistakes with Verbal I could get it back up close to a V45. After a month of light study, I took the test again and to my surprise I scored a 760 (V51, Q45). Bransen was instrumental in me achieving this score. His voice was always in my head as I prepped for my last attempt. It was money well spent to get advice and coaching that I couldn't get from a self-study prep course. Bransen even gave me some tips via email after our tutoring sessions had ended. I'd recommend GMAT Ninja to anyone who feels stuck or discouraged with their GMAT scores.

I reached out to GMAT Ninja at point in my gmat journey wherein I had spent almost 2 years studying using various sources. But after all this effort I was unable to improve my performance on the quant section and was scoring between Q35 to Q40 on official mocks.

Harry Duthie the tutor who I worked with helped me immensely in recognising the exact process related mistakes that I was committing. The perspectives and solutions that Harry bought in based on his prior experience really helped me my improve Quant score and become much more efficient in Verbal. Harry and Charles were both very accommodating to all my requests and very prompt in responding to all the queries.

I would definitely recommend GMAT Ninja for any looking to improve their GMAT scores.

It is quite difficult for me to write about GMAT Ninja, but more in general GMAT, without being emotional.
Probably it is because the application process took me so long. I am Italian and I hadn’t any clue of what English was until I finished my bachelor's. It took me almost a year and a half to go through the whole process: learning a new language, how to write a personal statement and, of course, the GMAT. And it has been a really important part of my development as a person.
In Italian “Terrific” is considered to be a false friend. “Terrificante” means terrifying, and I think these two words are perfect for describing the G-MAT. It could be ridiculous how this test digs inside you. It doesn’t matter how a good student you are (Concepts are important but pretty easy). To achieve a good result, you have to understand yourself, not concepts. It is both terrifying and terrific what you can discover by facing this test. I would definitely say that I feel like a new person after the G-MAT experience, and G-MAT ninja was the engine that let me do this.
So why are they the best – I would say the unique – prep test company out there? Probably a review would not be enough to speak about all the details. The approach that Charles has is something crazy. There is a lot of research on the way he (and of course the other tutors) teaches. Every part inside and outside the lesson(s) has its reason and more important is unique for every person. It was incredible that Bransen, who has followed me for “only” 6 lessons, seems to know me for ages after a couple of weeks. Sometimes he spoke some sentences that made me speechless. The way he knows my mental paths, my processes. The way he understood my fragilities and my weaknesses. But most importantly how he made me understand what to do to change my bad habits. I think it would not be possible without being obsessed with quality. Every step is thought to have the best response regardless of who the student is. Maybe I am going too far, but I would say that even the cost of the lesson is part of the lesson itself. I have not tried the Test Anxiety Program but from what I have read it seems to be the perfect child of this reality. I cannot even imagine how they work to build such a program.
Apart from these technicalities, if you decide to hire them, you will hire people who are not just smart, but who know the value of communication and active listening. It is clear that the first quality to be a G MAT ninja tutor is to be a good person.
If you want to maximize your score and discover something new about yourself there is no other choice apart from GMAT ninja.
Also, they have great taste in terms of food. So, you can be sure that your money will be spent wisely.
Thanks again to everybody there. Charles, Bransen and any other person that contributes to this wonderful project.

+80pt improvement with Dana! Read if you have test anxiety!!

Instructor Dana Stepleton

My GMAT journey started almost a year ago. I self-studied using Target Test Prep and exhausted almost all Official Guide materials and all the 6 practice tests. On all my practice tests, I scored between 720-780. In my first GMAT attempt at the test center, I scored a 660 (Q:49, V:31), which was a huge disappointment considering my practice test scores. I decided to re-take a month later, and was disappointed again with an even lower score of 640 (Q:49, V:23).

Given my decent Quant score, I knew I needed to focus more on my Verbal skills and decided to reach out to Charles, who I discovered through his famous Youtube videos and GMATClub posts. After sharing my history and practice test scores, he suggested the variance in my performance might be driven by test anxiety. While he couldn't guarantee a timeline for improvement, he recommended I work with Dana Stepleton to fine-tune my process to manage my test anxiety.

I cannot say enough positive things about my experience working with Dana (especially if you have test anxiety!). She's patient, empathetic, honest, and she knew how exactly to address my concerns in a productive manner as it related to test anxiety. More specifically, in order to address the anxiety, we trained on harder LSAT material, and cranked up the pressure by setting time constraints on practice sets to simulate a pressured test environment as best as possible. She also coached me through my thought process, especially when I started to feel the anxiety creep up on me, and trained me on strategies to refocus my attention on the problem at hand.

Lastly, the level of professionalism and commitment at GMATNinja is commendable - from my very first email to my post-exam debrief outside of our tutoring sessions, Dana and Charles have been incredibly responsive and invested in helping me get to my goal score.

I took a lesson with Dave Goldstein after I studied for a month and got a 720 on the official exam. My main issue was verbal and I had a non-native background with very limited proper English grammar education and I never read fiction books (though I picked up the professional usage of English on the job over ~4 years). I initially just used the MGMAT book, but after a month, I can feel that my progress was slowing down, the mere increase of familirty with question types no longer helps. That's where David came in, the most helpful thing in retrospect is that he instilled the correct way of practicing and pace of solving problems upon me. On the CR and RC sections, the sequence of reading articles, noting down key themes and answering questions, as well as practicing using more than a dozen LSAT test really helped me to be more comfortable on the exam. As we monitor the correct rate on the LSAT, the number just goes up over the course of a month. I think practicing is necessary, but to have someone where to pointing out exactly what you are doing wrong is incredibly efficient and allowed me to finish the whole GMAT workstream within two month (including one month with David), and save time for other improvements in my Bschool application. I highly recommend working with Dave if you are ready to follow his procedure and doing a lot of practice questions. In the end, you will gain a very systematic approach to verbal questions and confidence steamed from seeing your improvements week over week.

GMAT NINJA - from 640 to 710 (!) with Dana Stepleton

Dana was simply fantastic. Patient, systematic, methodological and tough - all the things that I needed to push my score from a none too exciting 640 to a reasonably respectable 710.

For quant Dana taught me key concepts but equally importantly, how to approach a problem and what was being tested. She also got me to stop randomly solving a problem before I had even thought about what I was going to do. The homework assignments really helped me get the basics down and practice so that the challenging problems became much easier. My quant went for a paltry 36 to a very healthy 48.

For verbal, Dana was instrumental in getting me to slow down again and learn how to properly eliminate answers. The SC section, where I struggled, was a lot easier after I went over the main grammar concepts with Dana. My Verbal score went from an OK-ish 38 to a pretty good 41.

I highly recommend taking lessons with Dana. A score of 710 was nowhere on the cards for me - but with Dana's help, I got there in a few months.

Harry and I mainly worked over CR and SC over the course of four sessions. Aside from being an absolute gem of a human being, Harry is also one of the most meticulous, passionate, and dedicated teachers I've had. I think it's safe to say that if he didn't press or force me to think harder each time I was sloppy, my CR would've been a disaster. I've literally seen myself become a better and more logical thinker over the course of the month or so that we worked together.

While our focus during the tutoring sessions was mostly CR and SC, Harry made sure I wasn't slipping up on quant and RC either - working with him made me realize just how many silly mistakes I tend to make, and what I should do to avoid them (which was instrumental in scoring a Q50). Harry was also super supportive throughout the entire process and helped me retain my sanity in the final week or so leading up to the test. Suffice to say, then, I highly recommend Harry to anyone who needs help on the verbal or quant side of things.

Working with Harry was the best decision I made during my GMAT preparation. During our time together, Harry instilled in me a systematic, gimmick-free process to attacking the GMAT that gave me the best odds at reaching my target score. More impressively, he tailored the sessions based on my weaknesses and delivered the sessions in a cordial manner. Lastly, when I had to travel halfway around the world in the middle of our sessions, Harry gladly accommodated my new schedule with a convenient session time. After two months working with Harry, I walked away with a 750!

P.S. Don’t be afraid to ask Harry for book recommendations!

The path towards completing the GMAT is indeed well trodden and well documented these days. Whether you are just starting this journey, or find yourself at an impasse like I did, I hope my example can offer you some guidance and encouragement.

My journey was long and at times a struggle. When I decided to take the GMAT, I knew that it was going to be tough, but I never anticipated how tough. The last time I had grappled with maths was at the age of 15 when I finished my GCSE's. Some 12 years later, with a language degree and brand consultancy career behind me, I set about learning Maths again from scratch. After 2 months I had studied the Manhattan Foundations Quant book from cover to cover and buoyed with confidence, sat my first mock....which was a disaster. 350. At this point I realised that if the GMAT was my Everest, I had yet to arrive even at basecamp.

Undeterred, I set about another month's study, concentrating my energies on the higher-level Quant questions, however further mocks showed only modest improvements. By this stage, deadlines for business schools were fast approaching and I realised I needed to reach out for help.

It was about early December 2016 that I was introduced to Michael Maietta, (@GMATNinjaTwo) via Charles Biblios, aka GMAT Ninja. Mike came highly recommended by Charles. As I was studying from the UK, I questioned whether working with a teacher based in the USA was a sensible plan. However, Mike quickly found a schedule that worked for me and we set to work via Skype.

From the moment we started, I knew that working with Mike was going to be a rewarding experience. He is both hugely talented, professional and insightful while at the same time bringing a level of fun and energy into the classroom that kept me looking forward to the next lesson (something I didn't know was possible with Maths!). He very quickly got the measure of me and created a plan that would build upon my foundation level and enable me to advance towards the harder questions.

Having achieved a top GMAT score himself, he was able to not only give me a secure grasp of the core Quant and Verbal topics, but also teach me those crucial time saving tricks that I wasn't able to learn from pouring over books or watching online videos (I had watched a lot of self-help videos to little avail!). As Maths was not a natural discipline for me, it was even more impressive that he was able to translate these concepts, at times very complex, into a language I could understand and use.

I also would not have prevailed were it not for Mike's remarkable ability to motivate and push me forwards. Given the size of the task ahead, it was easy on occasion to lose focus/spirit and whenever this happened, he would find a way to get me fired up again. His level of dedication to my cause was exemplary and far exceeded what I expected. This is a real string to his bow and again another reason why going down the tutor route paid dividends.

One final credit I would like to bestow upon Mike was his insight into the tactics of taking the test. Mike helped work towards my deadlines and had a solid strategy for using the precious Mock tests/ practice material. As the test date neared, he adjusted the intensity to ensure I was exam fit and was always conscientious of the external factors that would also play an important role in optimising my test day performance, such as sleep, exercise and diet. I trusted in his guidance and when the big day came, I felt as ready as I ever could be.

When I left the exam centre, I not only had a 280 point improvement over my previous scores (I'll let you be the judge of the scale of this improvement), but also a score that got me into IESE Business School, one of the top 3 business schools outside of the USA. So, if you're reading this and are thinking tuition might be something for you or you've hit an impasse and don't know how to move forward, I really can't recommend getting tutor support more. You can check both Mike and Charles' profiles on their GMAT Ninja web-page (google search). Thanks to Mike, the GMAT didn't stand in the way of my career aspirations. I am forever grateful.

GMAT Ninja is the best value GMAT tutoring service on the Internet. After studying for 4+ months (through OG, Manhattan Prep, Target Test Prep, you name it) and peaking at a 700 multiple times on the real exam, I knew that I had it in me to do better, but was completely burned out and lost as to how to achieve the results I wanted. Extensive research led me to GMAT Ninja. If their plethora of excellent free GMAT resources/videos on GMAT Club doesn't convince you they know what they're talking about, their firm support, tailored approach, and honest feedback will.

I worked with Mike Maietta. Mike was super funny, unflinchingly honest, and absolutely committed to helping me achieve my goal. After a certain point of mastery, the last frontier to acing the GMAT is really about mastering your own psychology. In my two months of tutoring with Mike, he pretty much busted every myth I had internalized in my previous study/Internet-ing/forum browsing. I thought I was "bad at math" and needed to work more on concepts (wrong). I thought I should try not to get more than X questions wrong in order to get a great quant score (wrong). Or that getting the first 10 questions right was critical for a high score (also wrong). With every myth and more, Mike patiently delivered examples from past students to dispel the idea that I needed to "game" the test, but rather focus on consistent execution and approach every time. I also appreciated that the GMAT Ninja folks recognize that tutoring can be an expensive investment, so they are thoughtful about how long they recommend you stay in tutoring once they feel like you’re ready (up to your own discretion).

Anyway, months later, armed with a 740, I ended up with admits to an HSW and multiple T10 schools with full rides. I’m confident my GMAT was a key contributing factor to those results. Thanks, GMAT Ninja, for being part of my journey – I recommend them wholeheartedly.

P.S. Charles, GMAT Ninja’s founder, is awesome and a spicy food fiend with great Thai recs, which was a fun surprise to chat about during my intake process!
