As a person with an engineering background, I sought help with the verbal section for the GMAT exam. I, therefore, embarked my MBA preparation journey by reaching out to Mrs. Dia Gerontoudi, who effectively guided me and helped me significantly boost my Verbal scores. In the end of our sessions, my Verbal score outperformed my GMAT Quant result (self-taught), a testament of the great support, tips and tricks and teaching effectiveness provided by Mrs. Gerontoudi – for which I am very grateful.
