In the event that the student has studied the past years in international schools, does the school rehabilitate him in the Arabic language from the beginning of the study?

It is well known that attention is given to Arabic in the international schools so when you move the student from foreign school curricula to the Arabic school curricula like ours. You find difficulty of using Arabic in the study of the rest of the subjects, therefore, the support classes which begin after the end of the school day. Arabic deepens Arabic language to the student to facilitate study and studying the rest of the subjects.
