According to ISI Citation Indexes, Bilkent ranks high not only in Turkey but also internationally in the number of published papers per faculty member. Starting from level (year) 1, courses in Statistics and Research Methods are required until level 3, over four semesters. All areas of our dorms, including student rooms, are cleaned on a frequent and regular basis by our ISO certificated contractors, according to health and hygiene regulations. In my opinion the best public schools are Middle East Technical University(METU) in Ankara and Bogazici(Bosphorus) University in Istanbul.
