While the language of instruction in some universities in Turkey is English, the main language of instruction in most universities is Turkish. Although Turkish language proficiency is a prerequisite for admission to many academic programs, it is also possible to be admitted to universities without knowing Turkish. After being accepted to undergraduate or graduate programs in many universities, international students are given the opportunity to attend Turkish preparatory courses. You usually get 4-6 hours of language lessons per day at different levels for a reasonable fee or in some cases free of charge. At the end of the preparatory class, all students take the exam and if they have a certain language proficiency, they accepted to start the program at the university.
