More testimonials from Bell Curves students...

  • 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.

  • Bell Curves is nothing short of AMAZING! After struggling with the GMAT twice and repeated courses with another test prep company, I was almost convinced I had reached my apex. It wasn’t until I began working with Akil Bello that I began to see major results. The Bell Curves' method helped my score jump 130 points and I couldn’t be more grateful. Bell Curves is hands down the way to go if actionable solutions to your GMAT woes are what you need!

  • 690!!!! 46 Quant and 39 Verbal……Yes that's right the GMAT is my B@$#...now! Up from a 5 freakin 30!!!! Thanks for all of the help!

  • 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!

  • 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!

  • 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! :-)

  • The combination of peer pressure and what I felt were terribly low SAT scores made the difficult college admissions process worrisome for me. Luckily, I was introduced to the Bell Curves team and my worries quickly vanished. Comfort quickly replaced anxiety as I learned innovative strategies and techniques. As a result, my score jumped 230 points! Today I can proudly say that I attend George Washington University and would definitely recommend Bell Curves to any student looking to conquer the SAT!

  • I scored a 690! Thanks to Akil and the Bell Curves team, I was able to increase my GMAT score by 130 points! Without Bell Curves and the invaluable insights and strategies they provided, it would never have been possible. Thank you!

  • Bell Curves not only boosted my SAT scores, but also my confidence, by teaching me better ways to approach the test. The strategies I learned helped me immensely!

  • 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'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 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.

  • 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.

  • 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!

  • 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.

  • 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.

  • 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!

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

  • 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.

  • Thank you so much for your visit today. Your presentation made it evident that our school needs to plan more effectively to incorporate strategies and awareness around the SAT and ACT. The helpful test taking strategies made our students realize they can achieve a higher score simply through familiarity with the test structure and scoring practices.  This workshop helped reduce test anxiety and gave students the information they need to strategically plan and set goals for attending the college of their choice. Your participation with our staff and students helped solidify the college going culture that we are trying to build at our school!
