Erfun's tutoring is efficient and perfectly tailored to your needs. I came to him feeling hopeless about the Quant, especially because I'd already taken a class. But he was able to dissect my weaknesses and develop a targeted plan that boosted my score into the 160s. I really appreciated his attention to detail, his emphasis on reasoning skills (this exam is about thinking, not math!), and the vast trove of study materials he has available. He's on the pricier end, but he's well worth it!

Erfun helped me get over the hump in GMAT Verbal! I was so stuck on Critical Reasoning and felt like nothing I did worked. I tried classes, a bunch of books, and even another tutor, but I was plateauing and almost felt like giving up. Fortunately, I found Erfun and he taught me CR and RC in a refreshing, easy-to-understand way that helped me see quick and large gains. Because of his instruction I was able to break 85 in Verbal and 715 on the real thing!

Erfun is the only GRE tutor you need! Not only is he incredibly knowledgeable, but also very flexible in his methods to match your learning style. I had 1 month to bring up my verbal score from a 155 to 164. Additionally, he helps you prepare mentally. It is through his guidance that I was able to keep calm through the experimental section and not let it unnerve me for the remainder of the exam. Thank you, Erfun!

Erfun played a crucial role in assisting me to achieve a competitive GRE score. Given the plethora of options available, I was unsure of what and how to study, which left me feeling overwhelmed. Erfun's straightforward approach was exactly what I required. He assigned me daily homework, supplied all the essential materials, and elucidated the strategies and content in a coherent, rational manner that immediately clicked with me. He adeptly tailored the sessions to suit my requirements, demonstrating his genuine concern for my success. Thanks to his guidance, I surpassed 325 and will be enrolling at CBS in the autumn. I am grateful, Erfun!

If you're on the fence, just go with Erfun. You won't regret it. He knows everything about the GMAT and teaches it in a way that really makes it click. I was having tons of issues on Quant and DI, and he developed a targeted, tailored plan of attack that really addressed my weak areas and helped me overcome them. With his help, I broke 700!

Erfun is the best tutor EVER he is so so knowledgeable. He diagnosed my weaknesses, provided me with effective strategies, and it totally worked!! I improved my score from V: 165, Q: 156 to V: 167, Q: 163. I felt a LOT more confident with the quant concepts after working with Erfun. He is really really effective. We had abt 11.5 hours of tutoring total and my score improved enough for me to confidently apply Round 1 to the top business schools. Erfun really knows his stuff and is a true strategist. He diagnosed my weak spots and taught me strategies to master the test. Thank you, Erfun!!!!
