More testimonials from Bell Curves students...

  • 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!

  • My daughter is so thankful for Bell Curves. She recently told me that Bellcurves is helping her with school and vice versa. I noticed that her quiz/test scores at school are more consistent and improved this year. Many thanks again! :-)

  • 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.

  • Bell Curves personal tutoring not only fit my unpredictable schedule but it gave me the confidence I needed to reach my goal and score a 640 on the GMAT! Thanks to Bell Curves I was just admitted to the Tuck School of Business at Dartmouth.

  • 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.

  • 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!

  • 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!

  • 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.

  • I spent a small fortune with the so called top GMAT prep companies on the street but they all fell short on helping me make any improvements on my score.  Then MLT MBA Prep staff recommended a tutor from Bell Curves.  Nothing quite comes close to the level of individual attention and improvement I received from my private tutoring sessions.  My score improved 150 points in just a few sessions. Unlike other companies, my tutor was able to hone in on my issues and quickly fix them.  He went above and beyond to help me achieve my target score.  Additionally, the Bell Curves books not only teach you the concepts you need to know but they show you the techniques to beat the exam. If you are shooting for a top GMAT score, Bell Curves is the bar none the best.

  • I just want to let you know that I took the GMAT last week and got a 770, a scaled score of 45 on the verbal and 50 on the Math. Thanks again for everything as your company definitely made this happen.

  • I'd like to sing praises to Akil, Bell Curves and most of all HASHIM! I know I was a difficult student, but your headaches were not in vain! So far I've been accepted to Darden, Fuqua, Stern and Tuck!!!

  • 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.

  • After 3 years of off and on studying, I finally beat the GMAT with a 160-point improvement! The best decision I made over the course of those 3 years was hiring Ajani Burrell to be my tutor. He taught me the ins and outs of the GMAT, from how to attack Data Sufficiency questions to how to effectively read Sentence Correction and Critical Reasoning questions. Most importantly, Ajani helped me to adjust my ingrained approach to each type of question so that I would be most effective in understanding and correctly answering the question. Ajani is the man! For anyone that's willing to work, Ajani will be your greatest asset. I highly recommend him to anyone who wants a great tutor. Thank you Ajani! Thank you Bellcurves!

  • 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!

  • 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.

  • 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 just wanted to update you on my admissions status. So far, I have been admitted to Wharton, Tuck and Fuqua. I am still waiting to hear from Chicago. My average isn't looking too bad! Thank you again for all of your help. I couldn't have done it without you!

  • 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.

  • 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!
