My experience with Dia Gerontoudi Prep Center was for the GRE and TOEFL exams and it was all positive both professionally and personally. I managed to get into one of the biggest universities in America, while I had positive responses from other universities of my choice. These are people with many years of experience in the field, who know how to do their job and offer excellent services at affordable prices. As far as Ms. herself is concerned. Gerontoudi, who teaches the VERBAL parts of the courses, knows her subject very well, shows great enthusiasm for her work, while the organization of the material and preparation tips were the key elements for my own success both on the GRE and and TOEFL. An excellent job is also done by the mathematician of the Prep Center, Konstantinos Karalis, who has passion, experience, offers a lot of material for study in the form of exercises, and makes the lesson very enjoyable. Also, they helped me substantially in the editing of the Statement of Purpose by offering useful advice and instructions, which plays a very important role for programs abroad and especially for PhDs in American universities that mainly interested me. Finally, on a personal level, the relationship with their students is not a seller-customer relationship, but a teacher-student relationship, while they were always available for any advice or questions I had even after the lessons were over. In short, this is one of the best options in postgraduate preparation, and I highly recommend it to anyone interested.
