You can take the exam elsewhere. Because the number of examination places and examination rooms is regulated, many students who study Korean can't choose their favorite examination place when they apply for the exam. Most candidates encounter this situation, in order to grab the test center, they can only choose other test centers to take the test, and there are often many restrictions on the distance. Successful candidates only have one chance to change test sites. At the same time, the premise of changing the test center is that you can't make any changes after registration, provided that your ideal test center has test space.
