More testimonials from Bell Curves students...

  • When you put them all together, 650+580+570=1810! YEAH! Thank you for putting up with my ridiculous schedule this summer and thanks for the classes and diagnostics and chance to better my grades!

  • Thank you Bell Curves for making my success on the GMAT a reality. I increased over 100 points since my prior official score. I broke into the 650+ range and scored over the 90 percentile on the verbal. Bell Curves filtered out the extra noise out there around the false GMAT tips and tricks. They provided structure on how to approach and deconstruct math and verbal questions so I always kept the 'real question asked' at the top of mind as I worked. Their approach to time management helped a lot, boosting my score 50 points once I adopted it. Their hands-on approach and emphasis on student participation helped me to understand the way the GMAT writers think and ask questions. I had personal tutoring as well. Third person observation of my errors and trends helped correct the way I studied and practiced for the GMAT. I highly recommend Bell Curves for your test prep.

  • I would just like to thank Bell Curves and Yanni for all your help with the GMAT. Also, I wanted to inform you guys that I recieved my acceptance letter from the University of Minnesota Carlson School of Business.

  • Thank you for everything that you did to help me. I was accepted to Georgetown, Cornell, Rotman, Babson, and IESE. I am very happy! I decided to move to Cornell and am getting ready to do so!

  • Studying for the GMAT was a long and often a trying journey for me. However, being on the other end of the process now, I see why people say that the key to success is consistency and perseverance. One-on-one tutoring helped me to hone in on gaps in both my knowledge and test taking strategy. Being able to identify and fill in these gaps gave me the confidence to achieve my goal score.

  • I really want to thank you and the entire Bell Curves institution for everything you have taught me because it has certainly paid off. Please tell Christina as well as everyone else that I really appreciate everything that they did for me this summer.

  • I worked with Ajani Burrell as a private tutor and he was extremely personable, patient, and encouraging. Even when I reached my lowest point in the studying process, Ajani continued to provide crucial guidance to help me push towards reaching my target score. In the end, Ajani and Bell Curve's ability to provide me with a more structured preparation process made all the difference. After trying 2 other GMAT prep companies, Ajani and Bell Curves provided exactly what I needed to break 700 on the GMAT.

  • Akil was the best because he had confidence in me, and required me to give my best. He helped my score improve 70 points, taught me on speaker phone when morning sickness kept me home, and kept the entire class laughing while navigating the stressful b-school process. Bell Curves endorser for life.

  • The GMAT is the ultimate hurdle to b-school, but Bell Curves provides a solid and customizable blueprint that makes the hurdle significantly less daunting. Bell Curves provides whatever you need, and they have a talented team of standardized testing experts that will diagnose your learning style to give you the customized instruction needed to beat the GMAT. My score improved by 150 points!

  • The intimate classroom environment facilitated networking and support among all involved. At a cost much less than that of many other GMAT prep companies, Bell Curves easily trumps other companies in value. I am extremely thankful for all that the Bell Curves staff has done to help me attain my goal of an MBA from a top institution!

  • Thanks so much for bringing Bell Curves to Atlanta. I am happy to report a 110-point increase in my score since taking your class! You guys rock!  

  • After taking a full GMAT course + private tutoring with Hany ElDiwany in the fall, I have nothing but great things to say about Hany's teaching/tutoring skills!!! He's very patient, quickly targets weak areas and follows up with various on the spot drills and questions to shore up those weaknesses. Hany is great at creating his own questions and strengthening & weakening retired OG quant questions to reach someone at the level they're at. Very unique skill set I must say. In addition, Hany was always available to answer questions via email 24/7 ( even while he was on vacation). Overall I can't ask for better service than that. Great experience all around!!

  • The website is one of the greatest assets at Bell Curves, because it imitates the computer functionality of the exam, which was something that I struggled with. The Bell Curves staff is very encouraging and supportive throughout the GMATpreparation experience and really keeps you motivated. The small class sizes and the emphasis on learning question types rather than specific questions were especially useful and helped my score.

  • It's all over!!! I got a 750!!! Sooooo happy! Couldn’t have done it without all of your help. The class was amazing...your advice, insight and feedback were priceless. The best money I’ve ever spent. Thanks so much!

  • I had literally tried everything before working with Ajani. I self studied, took a class, and hired a tutor, all to no avail. Ajani was my lucky charm. After working with him, I got the score that I needed to get into Stern, Columbia, Booth, and Cornell...I even got scholarship money!!!!   Ajani is a gem and the Bell Curves method works!

  • I had pretty much given up on the GMAT after doing a full-length course and a few hours of tutoring with 2 other test prep companies. After bombing the GMAT my first time (500, Quant 27, < 20%), a tutor from one of the “top” test prep companies reasoned that math was not my forte and that I should focus solely on the verbal to increase my score. I soon realized that he was a waste of my time and money because not only was his advice crazy, we had no formal meeting place, so tutoring sessions at Starbucks weren’t really effective. Fast-forward to me walking into the BC office a total anxious wreck. I purchased tutoring hours and began working with Ajani, who, let me just say, is nothing short of amazing! After reviewing my work from just 1 practice test, he was able to identify my weaknesses and repeated mistakes. Ajani was super patient with me and never made me feel like the idiot I was making myself out to me. Even with my stupidest mistakes, he would find a takeaway point from it…AMAZING! The BC books and online material were also extremely helpful. From the books I learned new, but really simple and reliable ways to attack each question type. The online CAT quizzes and exams were the most realistic practice questions that I’ve seen. On my actual exam, for some of the questions, I was thinking, “oh…this is just like such and such question from the BC material.”One of my biggest hurdles was my fear of the exam; working with Ajani and practicing on my own with the BC material really helped overcome this fear and I walked into the exam feeling confident…for the most part. All in all, my BC experience was beyond worthwhile. I regret not starting my prep with them initially. I truly believe that I would not have been able to conquer the GMAT without them. Final score – 650…got the horrendous quant raw score up to 42.

  • After not having a quantitative class in at least 7 years, the BC GMAT company and tutoring served me very well. It provided a comfortable environment where I could ask both simple and difficult questions. I not only received a basic refresher, but also study and test taking strategies. Now I have been accepted to 3 top 10 MBA programs!

  • Thank you so much! I feel like I have a game plan. The ten pages I did on perms and combs from the Quant manual have laid out quite a simple and clear foundation, so I look forward to my GMAT challenge!

  • Just wanted to send you guys a quick note to let you know that I was just admitted into Wharton!  Now I'm just waiting to hear back from HBS.  Thanks for all of the help you guys have given me to help make this a reality!

  • Bell Curves taught me how to avoid the kinds of mistakes on the SAT that were keeping me from reaching my full potential. Bell Curves helped me push my score beyond my goal of 2300 points – a plateau I was having trouble reaching on my own. In short, Bell Curves was a GREAT help. I could not have done it without them.
