I took a GMAT course with a well known academy in Madrid, but after finishing it I did not feel ready for the exam. After a few months studying by my own I still felt unready, but then a friend told me about Kevin, and how good he was at teaching the GMAT. I called Kevin and had 12 hours of private GMAT lessons with him. I took the exam and scored 710. Kevin has definitely helped me to achieve the score I wanted
