The YKS exam, also known as the Higher Education Institutions Examination in Turkey, is a widely recognized test taken by high school students to enter higher education institutions. There are several synonyms for the word YKS used interchangeably such as the Turkish acronym TYT (Temel Yeterlilik Testi), which refers to the exam's basic competency test, and AYT (Alan Yeterlilik Testi), which refers to the subject-specific competency test. Another alternative is the LYS (Lisans Yerleştirme Sınavı), which was previously used to refer to the exam before being replaced by YKS. These synonyms help in identifying and understanding the different aspects of the exam and its components.
