More testimonials from Bell Curves students...

  • 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.

  • I'd like to thank you [Jennifer O] for your help.  My SAT score improved from a 1560 (math-500, critical reading-560,writing-500 with a 6 on the essay) to an 1880 (critical reading-660,writing-620,math-600 with a 8 on the essay). I'm really happy with the improvement  Honestly, I didn't expect an almost 100 point improvement in every section. It went really well, and I just want to say thank you again.

  • I am happy to report that I am officially done with the GMAT, after increasing my overall score by 150 points! I am extremely thankful for my teacher Andrew and the entire Bell Curves team for the support. Before taking a Bell Curves course I completed a popular GMAT prep in person class, but I did not receive the results I was hoping for. Recognizing that I needed to approach my exam preparation differently I decided to enroll in a Bell Curves online course. This weekly course provided me with the necessary structure to succeed on the exam and taking the course online gave me greater flexibility with my schedule. The statistics provided after every practice exam and set of practice questions were extremely helpful, these results helped me craft a custom approach that helped me achieve such great improvements. My teacher, Andrew was also very accessible and great at answering my questions as well as helping me develop my strategy. Finally, the Bell Curves' approach, mastering one subject at a time helped me tremendously. I highly recommend Bell Curves to all those preparing for the GMAT!

  • 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!

  • Before taking a Bell Curves GMAT preparation course, I took the GMAT and received a score of 430. To get into the school I was interested in, I needed to raise my score at least 70 points. After taking the Bell Curves GMAT prep course, I raised my GMAT score 100 points to a 530. Thanks to this course, I have been accepted into Georgia Southern's MBA program where I will be attending classes this fall. The instructor was available and helped focus on my areas of weakness. The online materials provided with the Bell Curves prep course were extremely effective, since they were very similar to the questions on the GMAT itself.

  • 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.

  • 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!!

  • 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!

  • 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!

  • 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!

  • Just wanted to let you know that I got accepted in UCLA's Anderson School of Management! Thanks for helping me with that GMAT.

  • Hello, this is your student from last summer, Jennifer, from Columbia University's Mellon Mays program. I'm just writing to let you know that, after getting accepted to 5 English PhD programs for Latina/o literature and spending about a month torturing myself over a decision, I finally chose to go to the University of Michigan this fall on the Rackham Merit Fellowship. Taking that GRE prep course with Bell Curves was not only ridiculous amounts of fun, but also totally stress- and anxiety-reducing and I felt totally prepared walking into the exam. Seriously, thanks for all your help -- and I hope next year's Columbia Mellons have at least half as much fun as we did. :)

  • Dreams do come true! Despite the ease with which I typed that statement - please KNOW that the achievement of your dreams does not come without a lot of hard work. In comes Bell Curves: I have had an extremely positive experience with Akil and the rest of the Bell Curves team. I feel as though they had a genuine interest in my success and challenged me relentlessly. What especially stood out about Bell Curves is the team's emphasis on thinking conceptually about the GMAT and mastering your timing. I am blessed with the "problem" of deciding between Wharton, Chicago, Tuck and Fuqua.

  • Bell Curves has been more than just a GMAT prep company for me. Not only did I receive expert GMAT training that helped increase my score by 90 points, but I also received helpful insights into the overall MBA application process. These insights helped me establish a framework in which I was able to successfully be admitted into two of the top worldwide MBA programs.

  • 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.

  • Bell Curves really helped me narrow in on my weaknesses on the GMAT. After taking the Princeton Review with no improvement in my score I started to lose hope. After working with Bell Curves I was elated when I saw my score improve by 100 points! I now have a score that will give me a fighting chance in the admissions process and I am quite excited!

  • I just wanted to say thank you for all your advice on how I should prepare for re-taking the GMAT. I found the Bell Curves information and drills to be wonderful, and together with the Official Guide I was able to raise my score 70 points to a 700! Thanks so much!

  • Guys,      No longer shall the beast that is the SAT preside over my Saturdays. The beast is dead. As you know, I got: Critical Reading - 800, Math - 770, Writing - 800 (MC: 80, Essay: 11) 2370. That's right, College Board. Suck on that! Thanks a lot for everything. I couldn't have done it without you.

  • I wanted to share the good news that I have been admitted to Stern, Booth and HBS! Thank you for all of your help with regards to the GMAT and your advice of when to begin to focus on applications. I know that my GMAT score was an important component of my application and without your help I may not have achieved the score that allowed me to be considered at these schools. I truly appreciate your assistance and I look forward to beginning my MBA journey soon!

  • I have always found math intimidating, all the way through AP Calculus. So then, there it was, the math portion of the GRE, looming like a monolith between a PhD program and me. Luckily, the director of the Mellon Mays Undergraduate Program at Columbia University was smart enough to hire Akil Bello of Bell Curves test prep. Akil demonstrated all of the best qualities of a tutor: extreme patience, humor and unparalleled knowledge concerning the test at hand. Within a few short weeks I not only gained a greater understanding of the mathematical concepts tested by the GRE, but I also learned how to become a more efficient test taker over all, increasing my confidence and making test day a breeze. When faced with the daunting task of compiling my graduate school applications, it was a source of calm amidst the storm knowing that at the very least, I had the GRE in the bag.
