i got 166Q + 157V. My total score was 323. for quant: went through targettestprep condensed notes, then attempted all questions in magoosh 589 (make an error log). also went through manhattan 5 lb's number properties. i should've done more counting problems. for verbal: went through magoosh common + basic and saad amers list. attempted all short passages in the big book. also tried a few different butler questions from greprepclub to practice by question type. this helped me w SE and TC questions. butler questions are actual questions btw and one was even repeated in my actual test. attempted all SA mock and was averaging 2 mistakes throughout (got 3 wrong in my actual test) quant on my actual test was wayyyy more difficult than anything i had previously practiced on. verbal was easier. vocab from basic, common and SA's list was not exhaustive tbh but 100% enough for me to get by. i have never read a book and was horrible at vocab before this. all these lists are a MUST. the 341 page was amazing. i also got hold of his notes from somebody who took his classes. those notes had everything i needed to figure out how to attempt, order of questions, etc did all vocab lists in july (100 words a day is easy). started studying for quant on 25th july, finished it by 10th aug (which was previously my test date, but i deferred to 10th sept bec of lack of prep). verbal from 11th aug to 25th aug. 26 aug to 9th sept random practice (gre prep club questions) and mocks. so i spent about a little over 2 months on this. must go through the new exam format on the 341 page before anything else test day was all smooth and easy. drank a booster but should've had something w more caffeine must go through counting problems and understand logic more. these were a lot and i found them (always have) difficult make an error log for math questions so you dont make the same silly mistake twice. the error log should be concise and organized enough to be revised within 5 minutes.

I had a great experience working with Erfun to prepare for and take the GRE. Erfun has an impressive understanding of all aspects of the test, and taught me strategies to approach each part of the exam in the best way possible, from things like understanding how to time and pace each section, to how to handle more advanced test content. He provided me with a wealth of study materials and resources, and established a lesson plan for me to surpass my goal score in the few months I worked with him. Each session with him was efficient and productive, and Erfun tailored the sessions and homework according to my problem areas and questions. I highly highly recommend working with Erfun if you're looking for a tutor -- couldn't have done it without him!

I wish I'd found Erfun sooner. After wasting precious $ and time on other classes and books, I was stuck in the 500s and frankly felt lost in my studies. Erfun was honest but encouraging. He was quick to identify weaknesses I didn't even know I had to set up a syllabus we methodically executed over the course of my 8 weeks with him. I was honestly shocked at some of his insights and the unique and creative methods he used. I actually found myself laughing during our sessions, something I never thought would've happened with this horrible thing known as the GMAT. Overall, he helped me tremendously, ultimately yielding a 675 GMAT.

I'm applying to top business schools for Round 1, and I decided to get a headstart on my studying because I knew how tough the GRE would be. Erfun came highly recommended, and he lived up to his reputation. Starting with an initial diagnostic, he helped me build a strong foundation. From there, we moved into advanced topics, and finally practice tests. I was stuck in the high 150s, but with his help, I finally broke through to 326. I'm stoked and excited to apply to b-schools this fall!

Erfun's tutoring is world-class. As someone who always struggled on standardized tests, and especially math, I frankly felt overwhelmed by my GMAT studies. Despite over a year of studying (including other classes and tutors), I couldn't get over the hump. Erfun was crucial in helping me to do just that. He was direct and honest in his feedback, and he had insights into my approach and thought process that I never would've realized myself. He was so good at understanding the psychology of the exam and helped me understand what the test was really about and what was truly holding me back. I ended up with a score in the high 600s, which I simply don't think would've been possible without his help.

If you’re struggling with GRE quant and feel like it’s your mortal enemy, then look no further than Erfun. After trudging through countless classes and still feeling like a deer in the headlights every time I saw an equation, I was about to give up, but Erfun was almost like a savior. He didn’t just teach math; he made it fun. He turned intimidating problems into quirky puzzles and had me actually laughing (I kid you not, my roommate overheard me and couldn't believe this was a tutoring session!). His explanations were so clear that even the most complex concepts started to make sense, like magic. And he had the patience of a saint, never once flinching at my endless questions. Thanks to Erfun, I not only mastered quant but also gained a newfound confidence. If you’re in need of a GRE quant miracle, look no further. Erfun is pure gold!

Erfun helped me over the span of 3 weeks on GMAT preparation. With his help, I was able to improve my score 90 points to 700+ (compared to the most recent official exam which was three weeks prior). I began my GMAT preparation through a self-study course, but Erfun was able to help with the key test taking strategies that allowed me to better apply the knowledge I had learned throughout my studies. I would highly recommend him to anyone who is struggling with a plateau or needs to expedite their study plan. He provides a customized program that focuses on weaknesses and allows for more efficient learning. Thanks for the help, Erfun!

Erfun took me from a 319 to a 332. I couldn't be happier. Erfun's tutoring targeted exactly my weak points, and his amazing trove of GRE materials ensured that I always had practice available on good, realistic questions. Every session targeted my exact weaknesses and incrementally built up to the point that I was consistently scoring in the 330s on my practice exams. Can’t recommend him enough!

Before working with Erfun I just couldn't get over the hump in Quant. Online courses were helpful, but I was in a rut and didn't know how to proceed. I decided to work with Erfun because of his emphasis on reasoning skills and methods as opposed to just "math". This was truly the difference-maker for me. He showed me ways of thinking through the questions that had never occurred to me and gave me targeted homework that helped his methods stick. With his help, I hit a 685. Thanks, Erfun!

Erfun lives up to the hype! Not to be hyperbolic, but Erfun is nothing short of amazing. He's a world-class tutor, an expert in the GRE, and a master at understanding his students' psychology and getting them past any hurdles standing in their way. If you're struggling on the GRE and need some expert prep, he's your man.
