About Us

Testimonials: Test preparation

770 GMAT scorer


I am so grateful that Sue worked with me to achieve my result in the final examination – the contact sessions with her made a huge difference in preparing me. Sue made efforts to accommodate my busy schedule, and catered for my individual strengths and weaknesses so that we could focus on the biggest development areas from session to session. Sue shaped my appreciation for the strategic importance of the Verbal sections, and my improvements from the mock tests  through to the final GMAT Examination were off the back of improvements in my Verbal score.Sue inspired my best efforts and celebrated with me in my successes. Sue played a huge role in my final GMAT score, as well as the TOEFL examination

'Instructors' input was invaluable'

I found both Quant & Verbal components of the course extremely helpful they helped me pace my study programme and build my understanding quickly. I believe that especially on the Quant side the difficulty in the GMAT Official Guide is not representative of the exam.  The Verbal component was extremely important for me finally getting to grips with the expectations of the test.  It is difficult to learn the complex nuances for the different strategies of approaching the question types from a book. That’s why the instructors’ input was invaluable.


From 680 to 710


Thanks to Cara and Shimon from Coefficient Solutions I was able to improve my GMAT score from

680 to 710 in just two weeks. .I would highly recommend Cara and Shimon

to anyone doing GMAT. They really understand the nuances of the test and how, as South Africans

with little experience in taking adaptive tests, we can obtain competitive scores. Cara has also been

a huge help with the MBA admissions process. Thank you Cara and Shimon!


Testimonials: Application advice

HEC Paris and Yale

  Admissions Africa played a pivotal role in helping me get accepted into a Master In Management at HEC Paris and Yale. As my GRE score was lower than the average score at both schools and the program was highly competitive, I realized that I needed to craft a stellar application to stand a chance of gaining acceptance.

Throughout the entire process, Cara made me think more deeply about why the master’s program was an ideal fit for me and how I could best communicate this to the admissions officers at both universities. 

Thank you Admissions Africa for helping me get accepted into my dream program- I couldn’t have done it without your help and support!


The backbone of my applications

I applied to 5 programs and have been accepted into 3 (Emlyon/ St Gallen/ Maastricht) with 2 pending (Tias/EDHEC) where the interviewers told me they will give a positive recommendation so cautiously waiting for  good results. There are also some scholarships included.

This is not me bragging, this is me saying thank you to you and your colleagues. The advice and classes were really the backbone of my applications. Thank you very much.
