GMAT Compass

Erfun helped me get my score from 540 to a 690 over 4 months. I ended up getting into Stern and graduated back in 2015. I’m now making 7 figures. I owe a lot of it to Erfun helping me get over the first hurdle. The GMAT Compass program was well-organized, incremental, and tailored to my areas for improvement. Highly recommend to anyone liking to improve their GMAT score.

Erfun was referred by a former colleague who attended Kellog. I worked with Erfun for 8 weeks after scoring a 590 on my most recent exam at the time. I had scored a 710 6 years prior but had to retake the test as the score was now expired. It was challenging to get back into studying mode being 6 years out of undergrad and having a challenging work schedule. I had used the Princeton Review course but just wasn't getting beyond 650 on practice exams and was falling short on time as the b-school application deadlines were coming up. Erfun was amazing to work with. He takes a rigorous approach to putting together a tailored study plan focused on your weak areas and provides thoughtful guidance on when to schedule your next exam. In between sessions I always had content to go through and never felt lost on what to do next. During our sessions, Erfun would provide invaluable insight into approaching questions in a methodical manner that would not only save a ton of time, but also enable you to solve harder and harder questions. As the weeks went on I was making huge strides scoring in the low 700's on practice exams. However, I was having difficulties performing on the real exam. This is where Erfun's help truly made the difference. He helped me combat the testing anxiety by giving me tips on test day rituals, section ordering, break management, and just overall positive reinforcement. All the work we had done on the technical side and the approach to the exam ultimately came together, resulting in a 780 score! While Erfun's quant lessons were top notch, I want to particularly highlight his incredible verbal lessons. As a non-native English speaker from Western Europe, I struggled most with verbal before working with Erfun. Through dedicated reading comprehension and sentence correction sessions I was able to score a perfect 51 verbal score on my final test. I would recommend Erfun's services to anyone who is looking to either break the 700 range or further differentiate their b-school application through a 99th percentile GMAT score.

I can honestly say Erfun is an incredible tutor. He drastically diminished my crippling test anxiety and gave me tailored strategies based on my strengths and weaknesses that culminated in final score that far exceeded my expectations. I am more than pleased and attribute my test-taking success to him. After two back-to-back unsuccessful GMAT courses and an ineffective self-study program, I just couldn’t break the 600 mark. I studied for months and somehow managed to drop my score, probably from exhaustion and ineffective methodologies. I decided to invest in a private tutor to help evaluate what I was doing wrong and how to move my score to a minimum 650 mark to get into the schools I was aiming for. I found Erfun through an internet search and read the glowing reviews. I decided to give him a call to see if he lived up to the hype. At our first session, I was immediately impressed. He asked me a series of pointed questions to get to the heart of what was going on in my test taking strategy. Erfun was like a psychiatrist; he challenged my brain to determine my strengths logical reasoning and immense failures comprehension and memory. I could tell he was having fun in a relaxed and easygoing way. He made me feel at ease right away and made me laugh at the places I struggled with most. My fears and anxiety about the GMAT started to dissipate right away. I knew I could trust him to guide me through improving my score. In just the first hour, I felt like I gained a tremendous amount of knowledge along with specific assignments to address my weaknesses. He literally wrote the book on GMAT questions look it up - he’s credited as the author on the very GMAT prep books I struggled with in self-study. I knew after that I could trust him completely. Erfun was the first person to congratulate me on my GMAT score. He really cares about his students and is invested in our success. I was blown away by his abilities and demeanor initially and continue to be beyond impressed with his methodology. Oh and the final score? 700!

Great experience! I struggled for over a year with my GMAT studies. Manhattan Prep? Didn’t help. TTP? Same thing. Stuck in the low 600s, I came to Erfun. His structured, logical approach fundamentally changed how I thought about the GMAT and how I approached my studying. With his help, I scored 730. Thanks, Erfun!

I worked with Erfun in 2021 to study for the GMAT. He was a fantastic tutor and helped me achieve a great score that got me into my target schools. His ability to identify your strengths/weaknesses, structure a lesson plan around your abilities, and clearly and succinctly explain the the answers for each question/question type is unparalleled. He not only teaches the underlying theory for each topic be it quant or verbal, but also drills the importance of learning how to take the test with well-defined strategies for each question type. If I were to have studied by myself, I almost certainly would have overlooked the significance of identifying each question type and being strict in following the same strategy for each. A huge piece for me was having structure within my studying. Studying for the GMAT is daunting, especially with a full-time job, so having a plan was crucial. Erfun helped devise a study plan with quizzes/practice tests and a target for test day. He kept me on track with daily practice from his trove of questions as well as weekly assignments based on the current area of focus. Working with Erfun was definitely a worthwhile investment in my B school journey.

Erfun was massively helpful with my GMAT preparation and took the time to understand the errors I was making and putting together a plan to improve. His approach ensures all topics are adequately covered and addressed appropriately. My Quant ultimately improved from 38 to 48 and Erfun's support was an integral part of my improvement. I 100% recommend him as a tutor, particularly if you are serious about improving your GMAT score.

Erfun was an immense asset in my GMAT preparation. He took me from a 560 to 710 in about 12 weeks, which, in my opinion, is a pretty big increase and well worth the investment yes, he's not cheap. Before working with Erfun, I worked with another tutor in LA and took a big class, but neither one helped too much. Not that they were bad, but the teachers weren't terribly experienced a good score doesn't make you a good teacher!, and the curricula just seemed cookie-cutter. Enter Erfun: from session one, he created a customized syllabus that we executed through test-day. This was great, but, really, the most important part was his actual teaching. It's hard to explain, but Erfun has this incredible insight into the necessary strategies and thought processes to push through the harder questions. He was able to show me how to think clearly and effectively indispensable skills for the GMAT and to take a big-picture approach toward the questions. Think: less mindless math, more actual problem solving, planning, and strategizing. In addition, he has a trove of official materials categorized by topic and difficulty that enabled us to target the HW to my exact weaknesses. Very much worth the investment. Thanks, Erfun!
