 While the NUAT for freshmen and sophomores is held in March, June, September, and November, seniors take tests in March, April, July, and October to avoid overlapping with months when the CSAT Simulation is held (June and September).These two tests are appropriate for relative evaluations such as measuring average score, percentage, or ranks since the PCSAT has more similar sample groups to the CSAT than private mock tests do.The College Scholastic Ability Test Simulation (CSAT Simulation, ) is hosted by KICE, and unlike the NUAT, anyone who is eligible for the CSAT can also apply for this test.
