Fernando Serra de Souza

The GMATH method is 100% focused and based on the development of precise and effortless problem solving skills. Besides that, Fabio´s knowledge and passion for math transcends the exam and instilled a lasting appreciation for the subject.

Katharina Davies

Fabio´s teaching method and style are highly differentiated, and I can definitely say that they were essential to achieve the score I needed to get into top MBA programs. Simple ways to attack complex problems made all the difference!

Carlos Augusto Kawakami

The GMATH methodology is perfect. The course not only teaches the concepts but also helps the student in dominating theory, time and anxiety through mock exams and their performance analyses. Furthermore, knowledge acquired will be valuable for grad school and beyond.
