Tuition fees vary a lot according to the university, departments and cities. Tuition fees for Private universities are higher (for example, computer engineering ranges from 3 000-8 000 USD / Year) but public universities are lower. (For example, computer engineering varies between 200-500 USD / Year.) However, you have to pass the YÖS exam to enroll in public universities, and education is usually in Turkish language. Enrollment in Private Universities is done only with your diploma average and the language of instruction is English.
