Competition between international students is also played on linguistic mastery, especially of the English language. There is a competitive advantage for boys who started studying in international circles before school age (kindegarden) or who belong to bilingual families. In order to optimize efforts, the study of languages must not be done randomly, on the contrary, it must be carefully planned and organized to pass, from the first steps and with the necessary progression, international certification tests.
Certifications of various levels are required to access summer courses, to undertake interships abroad and to access international training programs.
