Dia Gerontoudi Prep Center not only offered me a top-notch GMAT prep experience but also a meaningful guidance for my future. Dia’s unparalleled knowledge on the subject and outstanding teaching methods guarantee effective delivery of the Verbal Part material. Similarly, Mr Karalis – with genuine interest in the subject and exceptional command in Mathematics-ushers students through the entire range of Quant-related topics and even similar future problems.

Overall my experience at Dia Gerontoudi Prep Center was remarkably positive due to the carefully structured course delivery, the resourceful, motivational learning environment and the highly skilled tutors-who also happen to be amazing people!

Thanks to Dia Gerontoudi Prep Center, I managed to secure a position at Brown University MSc in Innovation Management and Entrepreneurship and fulfill my dream to study and work in the United States.
