You will need a "student visa" to enter Turkey. Please make sure that you apply for the student visa at the Turkish Consulate in your country as soon as you receive your acceptance letter.
Make travel arrangements accordingly, so that you will allow adequate time for your visa to be processed prior to your departure.
Health Insurance in not a visa requirement for Turkey, however, students are recommended to have an international health insurance. Bilkent University has a well-equipped Student Health Center providing care for all students with their routine health problems and minor injuries.
