Students then may use the O-NET test score to apply to particular university through the direct admission system by taking tests conducted by particular university. However, most students still use the centralized admission system. In this system, they are expected to take another two aptitude tests, aiming at testing their ability to succeed in university. The first one is General Aptitude Test (GAT). GAT tests the reasoning ability and English proficiency of the candidates. It asks students to link and identity relationships between events. The English section is comparable to the TOEFL test, but is completely objective in nature. Both O-NET and GAT examinations are scored by computer.
