  • 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 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 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.

  • 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!

  • My scores were a 650 in math, a 650 in critical reading, and a 710 in writing. And my combined score ended up being a 2010, so I ended up achieving my goal to break 2000. I found my tutor to be fun and engaging, at the same time teaching the skills that I needed to know in order to succeed.

  • I took the GMAT again today (#5 I might add) and scored a 650!  This is a nice improvement over my highest score to date of 590.  I am pleased with the score and feel as though I did my best!!!  Thank you for all of your help man - I could not have done it without ya!!

  • 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.

  • 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!

  • 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! :-)

  • 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.

  • 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!

  • 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!

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

  • 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!

  • 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!

  • 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!  

  • 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!

  • 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'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!!!
