More testimonials from Bell Curves students...

  • 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!

  • 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 can't thank the Bell Curves Team enough, especially one Akil Bello, for all their expertise, patience, and support.  With their help I was able to conquer the GMAT to the tune of almost 300 points improvement!! They helped make all my hard work worthwhile. Thank you, Bell Curves!

  • 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 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!

  • I began the Virtual GMAT Course with Yanique this evening. She is WONDERFUL!!! Thank you for the opportunity to work with such a gifted and patient instructor.

  • 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 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 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.

  • Were not for Bell Curves' GMAT support, I might not have enrolled at Ross and sought to achieve the highest of aspirations. I certainly would not have cleared the "consulting bar" with my initial GMAT scores. Thank you for all that you've done and all that you continue to do in helping prospective MBAs succeed in the top business schools.

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

  • Enrolling with Bell Curves was absolutely one of the best choices I made regarding my business school applications.  I was able to raise my score from a 640 to a 710!  My instructor quickly and effectively determined my areas of weakness using Bell Curves’ innovative diagnostic tools. The Bell Curves curriculum is content-focused, which allowed me to truly understand the GMAT rather than try to game the system. If you want to maximize your return on investment, sign up with Bell Curves!

  • 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!

  • I found out this week that I've been ACCEPTED into Wharton's MBA program for Executives!!! I feel like Bell Curves had a big hand in helping me prepare adequately for the GMAT. Thanks again.

  • Thank you for sticking by me, and for pushing me to do better. The Bell Curves team has been an invaluable asset. Not only have I gotten THE BEST assistance preparing for the GMAT, but I’ve also gotten help with other facets relevant to the B-School process. Thank you Maestro and the Bell Curves Team!

  • 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!!

  • Thanks to Bell Curves - esp. Akil and Ajani - for helping me to achieve my goal of getting the score that I needed for entrance to graduate school.The classes were small enough to actively participate in all the learning sessions, and the online material (i.e. CAT quizzes, drills, and homework) was an excellent source of practice work. Thank you again!

  • 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!!!

  • 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.

  • Well, today was finally the day, and...I SCORED 710!!   I want to thank Bell Curves. Though I continued to use other study books, features of the Bell Curves site definitely made me more prepared. The CAT tests helped show how CAT scoring works, the review section helped me work on problem areas, I would have missed at least one question if I hadn't memorized the powers suggested. I could go on and on about how it's just a great site altogether.   I especially want to thank you Joe. You were always willing to help me with the many questions that I sent, you helped me find questions to target my problem areas, and you were very encouraging at the times when I couldn't hide my stress. I truly thank you. I could almost swear that at a stressful time during the test, I heard your voice telling me I'd be fine.
